Manufacturer CAD means geometry is imported from an identified source revision, with recorded exceptions. It does not certify physical production tolerances or later product revisions. Source dimensions means a reconstruction with a limited set of published dimensions; model identity alone does not verify connector positions or every surface. Envelope models represent outside dimensions only. Parametric designs have no specific original to copy.
- Bearing catalogs often confirm only bore, outside diameter and width. Ball/roller counts, raceways, cages, seals and locking details need manufacturer section drawings or CAD for each construction.
- Fasteners use nominal/standard dimensions; thread tolerance classes, runouts, chamfers and manufacturer-specific head profiles remain outside complete source verification.
- Gears, ball screws and linear guides need source tooth/raceway/recirculation geometry to certify internal detail; a valid mesh is insufficient.
- Motors, servos, cameras and flight controllers retain their individual source limitations. Unspecified mounting depths, connectors and internal parts must not be inferred as exact.
- Most electronics are packaging reconstructions. Source PCB dimensions do not verify port offsets, contact counts, component heights or board revision.
- Generic springs, structures, solenoids and lifting surfaces are design tools, not copies of a particular supplier product.
| Family | Presets | Manufacturer CAD | Sourced reconstruction / envelope | Parametric | Recorded limitations |
|---|---|---|---|---|---|
| Deep groove ball bearing | 2942 | 0 | 2939 | 3 | Sampled concave raceways, edge relief and closure faces make open, shielded and sealed constructions distinct. Ball diameter/count, groove conformity, seal lips and cage details are representative; supplier dimensions verify only the marked envelope and attributes. |
| Self-aligning ball bearing | 456 | 0 | 456 | 0 | Supplier presets identify the recorded envelope and construction options. Tapered bores use the nominal small-end diameter; an adapter sleeve is a separate component. Race profiles, rolling element size and count, seal profiles, cages and clearance gaps are prototype geometry. These are not manufacturing drawings. |
| Angular contact ball bearing | 240 | 0 | 240 | 0 | Supplier presets confirm the bore, outer diameter and total width only. Race profiles, rolling element size and count, contact geometry, seals, cages and clearances are simplified for spatial prototyping; these are not manufacturing drawings. |
| Double-row ball bearing | 31 | 0 | 31 | 0 | Supplier presets confirm the bore, outer diameter and total width only. Race profiles, rolling element size and count, contact geometry, seals, cages and clearances are simplified for spatial prototyping; these are not manufacturing drawings. |
| Double-row angular contact ball bearing | 259 | 0 | 259 | 0 | The common back-to-back double-row angular contact layout follows SKF and NSK sections. Only marked supplier dimensions and closure designations are verified. Ball count and size, contact angle, groove curvature, cage windows, sealing lips, filling slots, race chamfers and clearances are illustrative prototype geometry. Production filling-slot and split-ring variants differ internally; explicit split-ring, snap-ring and automotive assemblies require separate models. This model does not reproduce preload, manufacturing tolerances or load capacity. |
| Cylindrical roller bearing | 608 | 0 | 606 | 2 | NU, N, NJ and NUP layouts distinguish which ring carries retaining ribs. Roller size/count, cage windows and rib dimensions are representative. NUP uses a continuous inner-ring envelope; its separate loose collar and edge crowning are omitted. |
| Spherical roller bearing | 600 | 0 | 600 | 0 | Supplier presets identify the recorded envelope and construction options. Tapered bores use the nominal small-end diameter; an adapter sleeve is a separate component. Race profiles, rolling element size and count, seal profiles, cages and clearance gaps are prototype geometry. These are not manufacturing drawings. |
| Tapered roller bearing | 1480 | 0 | 1480 | 0 | Supplier presets confirm the bore, outer diameter and total width only. Race profiles, rolling element size and count, contact geometry, seals, cages and clearances are simplified for spatial prototyping; these are not manufacturing drawings. Inner-ring width B and outer-ring width C are approximated; use overall assembly width T for fitting. |
| Drawn-cup needle roller bearing | 201 | 0 | 201 | 0 | Catalog records identify the verified envelope dimensions and closure. NTN HK…LL construction uses two rubber lip seals retained inside the cup, with a shorter needle and cage assembly. Seal lip sections, race profiles, roller size and count, cage windows and clearances are representative geometry for spatial prototyping, not manufacturing drawings. The seals remain with the cup in the exploded view. |
| Rod-end bearing | 28 | 0 | 26 | 2 | Eye housing and spherical inner member with an unthreaded male shank. Supplier presets verify marked eye and nominal shank dimensions; spherical seat conformity, head outline and thread geometry are representative. Spherical articulation is not simulated. B is the inner-member width; the shank can make the overall assembly thicker. Origin is at the eye center. |
| Linear ball bushing | 41 | 0 | 41 | 0 | Supplier bore, outside diameter and length define the envelope. Ball size/count, retaining grooves, cage openings and seal sections are representative prototype geometry. Cutaway exports the displayed open housing. |
| Square-flange linear bushing | 19 | 0 | 18 | 1 | Supplier d/D/L values define the bushing envelope. Flange dimensions, when identified as sourced, use the linked manufacturer cross-reference. Manufacturer interchangeability and tolerances are not asserted. Balls, cage windows and seals are prototype internals. |
| Round-flange linear bushing | 14 | 0 | 13 | 1 | Supplier d/D/L values define the sleeve envelope. Mounting flange dimensions identified as sourced use the linked HepcoMotion cross-reference; manufacturer interchangeability and tolerances are not asserted. The flange has four counterbored holes. Ball return paths, cage windows and end wipers are representative prototype internals; extended variants use continuous return circuits. |
| Thrust ball bearing | 337 | 0 | 337 | 0 | Axial washers with sampled concave ball tracks and a separated ball row. Ball size/count, washer section and groove conformity are representative; cages and rated thrust capacity are not modeled. |
| Two-bolt flange bearing | 20 | 0 | 19 | 1 | Mounting face is Z = 0; the shaft follows Z. The model includes the mounting-hole pattern, tapered raised housing, crowned insert, offset inner ring and two seals. Marked supplier dimensions are preserved; casting fillets, reinforcement ribs, locking-screw holes and grease fittings remain representative or omitted. Not a rated bearing or detailed casting drawing. |
| Four-bolt flange bearing | 72 | 0 | 71 | 1 | Mounting face is Z = 0; the shaft follows Z. The model includes the mounting-hole pattern, tapered raised housing, crowned insert, offset inner ring and two seals. Marked supplier dimensions are preserved; casting fillets, reinforcement ribs, locking-screw holes and grease fittings remain representative or omitted. Not a rated bearing or detailed casting drawing. |
| Pillow block bearing | 109 | 0 | 109 | 0 | The origin is at the shaft centre, with the shaft along Y and the foot at Z = −H. KP08/KP001 use supplied drawing dimensions; the cast contours, bearing internals and unthreaded socket set screws are illustrative. KP001 B = 14.5 and S = 4 place the insert asymmetrically, so the complete depth is 18.5 mm although the housing base is A = 16 mm. KP08 insert width/offset are not published. Mount holes follow drawing N, which conflicts with the supplier bolt labels. UCP crown, base thickness, insert section and unspecified slot dimensions remain representative. No rolling elements or self-alignment simulation. |
| Insert bearing | 128 | 0 | 128 | 0 | Supplier envelope and marked shoulder dimensions only. Outer-seat curvature, seal sections and symmetric inner-ring extension are representative. Set-screw holes, rolling elements, raceways and locking screws are omitted. |
| Drawn-cup one-way clutch | 11 | 0 | 11 | 0 | HF-style envelope without an inner ring. Rollers touch the nominal shaft envelope; cup wall, count and spacing are representative. The cup includes a repeated cam-ramp cavity. Ramp angles, springs and cage details are not manufacturer specifications, and the model does not simulate locking operation. |
| Ball-bearing sprag clutch | 32 | 0 | 32 | 0 | CSK construction combines a ball bearing and a separate sprag row. The source-verified envelope and keyseat dimensions are preserved. Ball/sprag counts, cam contours, cages, groove conformity, seals and aligned key clocking are illustrative prototype geometry. Internal clearances prevent intersecting solids; this model does not simulate wedging, torque capacity or manufacturing fits. Manufacturer reference key dimensions are defaults only when the supplier has no dimensions; CSK 8/12 outer keys are editable examples. |
| Cylindrical thrust roller bearing | 15 | 0 | 15 | 0 | Supplier overall envelope and shaft-washer thickness. Both washers use that thickness in the simplified model. Roller count, length, equal washer bores and raceways are representative; cage and load rating are not modeled. |
| Spherical thrust roller bearing | 41 | 0 | 39 | 2 | The spherical housing raceway, inclined asymmetric barrel rollers and conical windowed cage distinguish this family from cylindrical thrust bearings. Supplier presets verify only d/D/T. Washer sections, roller size/count, cage shape, contact angle and raceway conformity are representative; the assembly is not a load or self-alignment simulation. |
| Combined needle and ball bearing | 2 | 0 | 2 | 0 | NKIB envelope with verified inner raceway and outer-ring widths. The split inner ring, angular-contact raceways, needle geometry, counts and cage are represented schematically. The model is for integration, not load or contact simulation. |
| Combined needle and thrust roller bearing | 6 | 0 | 6 | 0 | ZARN layout follows the Schaeffler section: a radial needle bearing between two opposing axial cylindrical roller sets, shaft washers and a continuous through-bore race. Only marked supplier dimensions are verified. Needle diameter/count, cylindrical roller profiles/counts, cage windows, internal race diameter and small assembly clearances are illustrative prototype geometry. This model does not reproduce preload, manufacturing tolerances or load capacity. |
| Spherical plain bearing | 117 | 0 | 117 | 0 | Supplier bore, outer diameter and ring widths. Spherical seat radius and clearance are representative, sampled in the meridian. Lubrication grooves, split outer ring, seals, articulation travel and contact stress are omitted. |
| Adapter sleeve with locknut | 56 | 0 | 56 | 0 | Supplier assembly envelope, nominal bearing seat and nut thickness. Taper, split and notch details are representative; threads are smooth and the locking-tab washer is omitted. This is not a thread-fit or installation-force model. |
| Radial shaft oil seal | 68 | 0 | 68 | 0 | Only nominal shaft diameter, housing diameter and width are supplier-verified. Case thickness and lip cross-section are representative. No garter spring, interference, elastomer deformation, pressure rating or exact seal-type claim is included. |
| Wing screw | 117 | 0 | 117 | 0 | Nominal supplier dimensions with a faceted forged-wing profile and smooth thread envelope. The head base is an editable square envelope. DIN 316 source h and overall-length rows disagree, so head height and wing taper are not marked verified. No load rating or manufacturing certification is implied. |
| Swing eye bolt | 187 | 0 | 187 | 0 | The source nominal length runs from the tip to the eye centre. The flat eye, bore and transition are tessellated consistently in the preview and CAD; the thread is a smooth nominal envelope. Transition fillets and manufacturing tolerances are not modelled. |
| Lifting eye bolt | 18 | 0 | 18 | 0 | Dimensional layout model with a circular ring cross-section, cylindrical collar and smooth thread envelope. Local forged transitions and certification details are omitted; this model does not establish a lifting capacity. |
| Bolt or screw | 2568 | 0 | 2560 | 8 | Prototype geometry, not a DIN/ISO certification. Modeled threads use a truncated single-start 60° reference profile without fit tolerances or runout. Cross and six-lobe recesses are dimensional approximations, not certified Phillips or Torx tooling profiles. Rounded heads use a sampled dome profile. Slotted drives are closed pockets. Countersunk length includes the head; other bolt lengths are measured under the head. STL is a closed tessellation; FreeCAD cuts a swept helical groove into a solid blank. |
| Set screw | 474 | 0 | 470 | 4 | Prototype reference, not a certified fastener. M2.5 × 8 uses the requested DIN 914 cone-point format. DIN 915 black steel references retain the supplied M2–M16 dimension rows and stated grade 12.9. Their overall lengths and shoulder chamfers are editable prototype choices; the image supplies no stock lengths. Socket nominal sizes and printed tolerance intervals are retained separately, including source inconsistencies. Material strength is not modeled. The thread is a truncated single-start 60° reference with no fit tolerances. Overall length includes the point and its shoulder transition. Cup recesses are conical. |
| Thin hexagon nut | 25 | 0 | 25 | 0 | Supplier presets preserve the listed envelope dimensions. Edge chamfers and unspecified collar details are editable prototype geometry. Internal threads use a truncated 60° basic metric profile without fit tolerances or runout. Smooth envelope mode is available for fast layout. Nylon inserts retain their undeformed smooth bore; the metal body carries the modeled thread. |
| Wing nut | 9 | 0 | 9 | 0 | DIN 315 American-form outline. Supplier presets use the published maximum d2/e/h/m envelope; material variants share that dimensional preset. Wing thickness, faceted curvature and body taper are representative. Internal threads use a truncated 60° basic metric profile without fit tolerances. Smooth envelope mode is available for fast layout. |
| Lifting eye nut | 10 | 0 | 10 | 0 | Supplier nominal d2/d3/d4/e/h/k dimensions define the envelope. M6 is explicitly marked non-standard in the source drawing. The ring section, tapered nut base and forged transitions are simplified. A modeled basic metric internal thread opens through the nut base into the eye. Fit tolerances and forging details are not specified by this model. This geometry does not establish a lifting capacity. |
| Coupling nut | 14 | 0 | 14 | 0 | Supplier presets preserve the listed envelope dimensions. Edge chamfers and unspecified collar details are editable prototype geometry. Internal threads use a truncated 60° basic metric profile without fit tolerances or runout. Smooth envelope mode is available for fast layout.

| Square washer | 8 | 0 | 8 | 0 | A geometric envelope for prototype layout. Spring force, tolerances and surface finish are not modeled. |
| Conical spring washer | 7 | 0 | 7 | 0 | A geometric envelope for prototype layout. Spring force, tolerances and surface finish are not modeled. |
| External tooth lock washer | 15 | 0 | 15 | 0 | Tooth count and depth are prototype choices unless explicitly listed as verified dimensions. Teeth are planar; stamped tooth twist is not modeled. |
| Threaded rod and stud | 78 | 0 | 78 | 0 | Stock lengths use a smooth nominal thread envelope for fast assembly layout. Detailed threads are limited to 80 turns; shorten the cut length before enabling them. No drive recess is present. |
| Hexagon nut | 34 | 0 | 34 | 0 | Supplier presets preserve the listed envelope dimensions. Edge chamfers and unspecified collar details are editable prototype geometry. Internal threads use a truncated 60° basic metric profile without fit tolerances or runout. Smooth envelope mode is available for fast layout. Nylon inserts retain their undeformed smooth bore; the metal body carries the modeled thread. |
| Flat washer | 131 | 0 | 131 | 0 | Flat annular geometry without edge chamfers. Check fit and clearances for your application. |
| Retaining ring | 130 | 0 | 127 | 3 | Editable circlip geometry with round lugs. Source presets use supplier free-ring diameters and thicknesses. Bore offset, lug rounding and unspecified holes are prototype settings, not DIN groove-fit specifications. Check the mating groove and free-ring size separately. External/internal chooses lug direction; elastic installation is not simulated. |
| E-type retaining ring | 16 | 0 | 16 | 0 | The supplier verifies DIN6799 nominal groove size. REYHER supplies the maximum outside envelope and thickness reference; American Ring supplies the free contact diameter reference. Lug angles and relief curves are representative. The resulting outline combines a free contact opening with the maximum outside fit envelope; installed elastic deformation, groove tolerances and retention capacity are not simulated. |
| Split spring lock washer | 24 | 0 | 24 | 0 | Gvyntok presets verify the nominal screw size only; their pages do not identify DIN127 or a dimensional form. Profile dimensions use explicitly attributed Güde DIN127-B maximum reference envelopes. The split angle and sharp rectangular ends are representative. Flattening holds the radial envelope fixed and does not predict spring force, preload or resistance to loosening. |
| Slotted spring pin | 95 | 0 | 95 | 0 | Nominal diameter, wall and chamfer ranges follow the linked supplier drawing. Slit angles are editable prototype choices. Free and installed states are geometric envelopes, not a press-fit force simulation. Curved surfaces are polygonal in both exports. |
| Split cotter pin | 141 | 0 | 141 | 0 | Supplier presets use the linked DIN 94 drawing: maximum shank and eye widths, approximate eye length, and minimum unequal-leg projection. The eye has a continuous half-round cross section. Eye transitions, small leg clearance, square-cut tips and installation bends are prototype geometry. Bending preserves each flat-surface path length; it does not simulate material deformation. Curved surfaces use polygonal sections. |
| Compression spring | 4 | 0 | 0 | 4 | One continuous round-wire solid. Reduced-pitch ends are unground and retain a small clearance. State changes describe assembly geometry, not force, stress, fatigue or telescoping contact. |
| Extension spring | 4 | 0 | 0 | 4 | One continuous round-wire solid lofted through circular sections along the preview curve. Its surface is segmented along the path. Full eyes retain an opening with clearance from the lead; they are not welded closed. The body has clearance between coils; initial tension, force, stress and hook-forming allowances are not calculated. |
| Torsion spring | 3 | 0 | 0 | 3 | One continuous swept wire with tangential legs. State changes preserve approximate circumferential wire length and body height. This geometry does not predict torque, stress, fatigue or material behaviour. |
| Double torsion spring | 2 | 0 | 0 | 2 | One continuous round-wire solid lofted through circular sections; the surface is segmented along the path. Coils are separated along a shared axis and have opposite winding directions. The inner end gap is measured between wire centrelines; clear gap is smaller by one wire diameter. Bridge reach is measured before its semicircular bend. State geometry is illustrative, without torque or stress calculations. |
| Flat spiral spring | 3 | 0 | 0 | 3 | An open flat strip with square-cut ends. The spiral outline is sampled at 96 segments per turn in both preview and FreeCAD. Mounting slots, preload, force, torque and wound-state deformation are not modelled. |
| Worm drive | 3 | 0 | 0 | 3 | Axial module sets pitch and lead; ratio = wheel teeth / worm starts; nominal center distance = (worm pitch diameter + module × wheel teeth) / 2. The worm has modeled trapezoidal helical flanks. The wheel uses a sampled concave throat with inclined involute teeth; it is not a conjugate hob-generated tooth surface. Use this pair for layout and motion studies, not for a rated or interference-free transmission. No shafts, bearings, lubricant film or self-locking prediction. |
| Spur gear | 7 | 0 | 4 | 3 | Small pinion layout mode allows undercut-range tooth counts using radial root relief, without reproducing the manufactured root or profile shift. Sampled involute flanks with radial root relief, circular tips and roots; no cutter-generated root fillets or profile shift. The selected shaft profile is an editable prototype fit. Pair equal module and pressure angle. Validate strength, fit and running clearance before use. |
| Helical and herringbone gear | 3 | 0 | 0 | 3 | Normal-module involute profile with radial root relief. Helix surfaces use short ruled loft sections; herringbone has no center relief groove. Parallel-shaft mates need equal normal module / pressure angle and opposite helix hands. Prototype geometry, not a rated transmission. |
| Bevel gear | 3 | 0 | 0 | 3 | Layout approximation: a planar involute profile is scaled along the axis. This is not a generated bevel tooth surface and is not guaranteed to mesh. Use for envelope and shaft-placement prototypes only; axial width is not cone face width. |
| Bevel gear pair | 31 | 0 | 31 | 0 | Six mounting references cover twelve table rows. The m2 15/30 listing adds 25 configurations of separately sold gears: pinion bores 8/10/12/14/15 mm without a keyway, and wheel bores 14/15/16 mm with a 5 mm keyway or 18/20 mm with a 6 mm keyway. Keyway depth remains an editable prototype dimension. The origin is the intersection of the 90° shaft axes. Teeth use a faceted, tapered involute-like layout profile; pressure angle, tooth corrections, root fillets and set screw thread sizes are unspecified. This geometry does not establish conjugate contact or supplier interchangeability. |
| Straight gear rack | 3 | 0 | 0 | 3 | Straight flanks, 1-module addendum and 1.25-module dedendum; sharp tooth roots without cutter fillets. Match pinion module and pressure angle. Pitch line is 1 module below the tips. No mounting holes or strength rating. |
| Profile linear guide | 8 | 0 | 8 | 0 | MGN presets use published mounting envelopes. Two closed ball circuits include loaded rows, return rows and semicircular end turns. Internal clearance chambers are representative open sections, not manufacturer return-channel tooling. Cutaway removes half the carriage. Ball diameters/counts, end retainers and threaded mounting bores are not production specifications. |
| Round shaft guide | 2 | 0 | 0 | 2 | Custom round-shaft assembly with four closed ball circuits, a slotted return cage and end wipers. The cutaway exposes the insert inside the bored housing. Ball sizes/counts and clearance chambers are representative; presets are not manufacturer-verified bushing or housing dimensions. Clearance is radial. |
| Ball screw assembly | 230 | 0 | 219 | 11 | Catalog dimensions apply only to the fields marked by each preset. Circular raceway clearance, loaded ball spacing, deflectors, return covers, preload spacer and lubrication pilot bore are representative prototype geometry. C5/C7 is requested accuracy metadata, not a manufacturing certificate. Overall shaft length includes machined journals; their dimensions are editable custom values. Positive rotation translates the nut by one lead per revolution. Continuous return routing and production contact profiles are not modeled. The inspection cutaway is offset by 0.001 mm to keep periodic CAD faces robust. |
| Ball screw nut | 131 | 0 | 129 | 2 | Source-backed presets identify the dimensions transcribed from their drawing. Loaded ball spacing, circular raceway clearance, return features, preload spacer, and blind lubrication pilot bore are prototype details. A family name alone does not verify the remaining dimensions or certify a production nut. The inspection cutaway is offset by 0.001 mm to keep periodic CAD faces robust. |
| Ball screw linear actuator | 6 | 0 | 0 | 6 | Prototype axis assembly. Screw/nut and MGN rail envelopes use the selected catalog rows; base, saddle, risers, support bearings and machined journals are custom layout geometry. End bearing rings represent clearances, not a bearing selection or load rating. Table travel is limited to clear both screw supports. The fast envelope omits screw raceway balls; choose helical detail to inspect them. |
| Flexible jaw coupling | 38 | 0 | 38 | 0 | The attached HLTNC listing specifies only the D25 L30 envelope and shaft bore pairs. Jaw sections, six-lobe spider, clearances, slit and low-profile clamp screws are editable prototype geometry. Clamp bores and shafts are smooth; threads and manufacturing fits are omitted. Rigid assembly and exploded states show construction without simulating torsional stiffness or misalignment. |
| Open enclosure | 3 | 0 | 0 | 3 | Open top, square corners and a uniform floor. Add application-specific mounting posts, connectors, fillets and print clearances in FreeCAD. |
| Servo horn | 28 | 0 | 28 | 0 | All dimensions are millimetres. Socket tooth count and both diameters are independent; a 23T, 24T or 25T label does not guarantee fit. Straight-flank socket serrations are a prototype approximation, not a manufacturer spline specification. Linkage and clamp bores are smooth; drawing thread callouts are recorded in source details. Only explicitly listed source dimensions are verified; other preset dimensions are editable prototype values. Clamp screws export as separate FreeCAD components. |
| Servo spline gear | 16 | 0 | 13 | 3 | External teeth use sampled involute flanks. The internal serration is an editable prototype envelope: tooth count alone does not establish servo compatibility. Socket diameters, depth and screw-head recess are not dimensioned in the supplied drawings. Measure the actual servo shaft before manufacturing a mating part. |
| Clevis fork | 24 | 0 | 10 | 14 | The 25 × 7 mm pushrod reference verifies its 3 mm fork gap, 2 mm rod bore, M2.5 pin screw and M3 set screws. Fork depth, pin setback, clearances and hardware sizes are editable prototype assumptions. Cable presets verify only the listed cable diameter. Threaded variants are prototype examples, not a named standard. Modeled rod threads use an untoleranced basic 60-degree profile; pin, nut and set-screw threads remain smooth envelopes. The cable terminal is a simplified fixed fork with a set-screw barrel; no swivel, swage qualification or rated load is modeled. |
| Piston | 12 | 0 | 8 | 4 | Listing sizes are nominal labels, used as editable cylinder-layout dimensions. Finished skirt diameter equals nominal size minus diametral clearance; the source does not establish running fit, alloy, tolerances, thermal growth or pressure rating. Compressor/engine bodies have an open skirt, pin bosses and a solid crown. Rings and clips have rectangular prototype profiles; pneumatic seals are uncompressed circular O-rings. Grooves and bores are smooth; no oil drains, asymmetric skirt, valve pockets or production sealing profile is inferred. Every displayed physical item exports as an independent FreeCAD solid. |
| Connecting rod | 8 | 0 | 0 | 8 | All presets are editable dimensional examples. The supplied anatomy and exploded illustrations establish component names and arrangement only. No engine fit, supplier dimensions, standard, strength, fatigue life or load rating is claimed. Pin and journal bores are finished working diameters; fitted inserts enlarge the rod housing by their thickness and the chosen clearance. Bolts and nuts use smooth thread envelopes. Small geometric clearances separate components. No oil channels, bearing locating tangs, fillets or balancing/mass target are modeled. |
| Angle bracket | 3 | 0 | 0 | 3 | Square internal corner without a bend radius or gussets. Hole centers follow the bracket envelope. Add fillets and verify load capacity for the intended material. |
| Round spacer | 3 | 0 | 0 | 3 | Unthreaded through bore with square ends. Dimensions are nominal and do not include manufacturing tolerances. |
| T-slot aluminium profile | 48 | 0 | 48 | 0 | Straight extruded cross sections from the supplied reference drawings. Open T/C slots and internal bores run through the entire cut length. Dimensioned sizes are retained in reference metadata; unlisted cavity dimensions, bore positions, small radii and step details are editable prototype settings. EU1030 measures 29.8 × 9.9 mm. EU1540 is a descriptive label for the 40 × 15 mm drawing. Listed cut lengths 50–550 mm apply only to EU1020/1030/1040/1050. Other initial lengths are prototype choices. Supplier mass per metre is recorded without inferring alloy, strength, extrusion tolerances or production fit. |
| Utility wheel | 3 | 0 | 0 | 3 | The preview distinguishes tire and rim with color; the FreeCAD assembly separates the tire from the fused rim and hub. Smooth tire with no tread, bearings, keyway or axle retention. |
| Holding electromagnet | 5 | 0 | 0 | 5 | Geometric prototype, in millimetres. The rear mounting face is Z=0 and the working pole face is +Z. The coil is a single potted winding envelope, leads are insulated envelopes, and the mounting bore is smooth. Presets are editable examples with no manufacturer, voltage, current, thermal or holding-force rating. The air gap changes placement only; no magnetic simulation is performed. |
| Tubular solenoid | 6 | 0 | 0 | 6 | Prototype geometry, not a supplier specification. The coil is a solid winding envelope; individual turns, electrical ratings, force, insulation performance and a return spring are not modeled. Both actions attract the armature toward the rear pole: pull retracts the front rod, push extends the rear rod. Retracted and extended describe output protrusion. The housing remains centered on the Z axis; dimensions include rods and terminals. Export creates a separate solid for each physical component. |
| Open-frame solenoid | 5 | 0 | 0 | 5 | Prototype mechanical envelopes. The winding is a solid annulus, not individual insulated turns. Presets are design examples without manufacturer, voltage, force or thermal ratings. The fixed pole retains a positive gap from the retracted plunger; the extended plunger remains engaged in the guide. Mounting holes are plain through holes. The optional rod is fused to the moving plunger. The model does not predict electrical performance. |
| Servo motor | 8 | 1 | 7 | 0 | Servo models have fixed manufacturer dimensions and read-only published specifications. Filters select matching models; they never resize a servo or change its torque/current rating. Case heights follow the dimension drawings; undimensioned casing details, mounting cutouts, threads and most optional horns are fixed visual approximations. KST A/B mounting patterns and ST3215 supplied discs remain distinct. See each model source and specifications for dimension discrepancies and measurement conditions. Current ratings are omitted where absent or ambiguously specified; missing values are not zero. Output angle changes geometric placement only, with no motor or electrical simulation. |
| Wing and control surface | 14 | 0 | 0 | 14 | E387, S1223 and NACA 23012 use UIUC tabulated coordinates with linear interpolation. Each surface is normalized from its shared leftmost sample to its trailing edge; the line from that sample to each trailing-edge endpoint is subtracted to close the trailing edge. This explicitly modifies finite-gap source profiles; user edge thickness is additive. Geometric concept models, not aerodynamic, hydrodynamic or structural qualification. NACA sections use the closed trailing-edge coefficient −0.1036; a nonzero trailing-edge thickness further modifies the profile. Double-wedge and biconvex sections represent sharp-edge profile families often studied for supersonic flow, without a certified speed range. Root/tip profiles are linearly blended in normalized coordinates. Sweep is measured at quarter chord; incidence and twist rotate about local quarter chord. X runs toward the trailing edge, Y along span and Z upward; vertical orientation rotates the complete geometry about X. Dihedral offsets section centres without changing their chord planes. Elliptic taper retains a finite tip. Native CAD uses ruled lofts of sampled polygonal sections; increasing divisions improves geometric resolution. No spars, hinges, mounts, materials, lift/drag, stall, flutter, cavitation or strength calculations are supplied. Presets are editable examples, not proven aircraft or marine components. |

These are mechanical layout references, not certified mating or replacement SRS hardware. Amphenol family codes do not specify ordering suffixes. Leads have illustrative colors and no electrical pinout. Separate mating retainers are not included in these connector models. TE contact positions, nozzle and locking details are illustrative; the brochure dimensions only the outer envelope. |

Wrapper seams, end folds and label regions are illustrative, not dimensioned in the source. Connector type is not specified by this series table. Published C-rate is not a verified harness current rating. |
| Li-ion cylindrical cell | 6 | 0 | 6 | 0 | Maximum cell envelopes from current manufacturer product pages. Flat-top unprotected cells only; protected and button-top versions have different lengths. Cap, gasket and rolled-rim details are approximate. Electrical ratings require the linked model datasheet conditions; no internal cell construction is modeled. |
| Primary battery | 8 | 0 | 8 | 0 | Maximum industry-standard envelopes from Energizer drawings. Button diameters use published maxima and projections use published minima; other rim and gasket details are approximate. The 9V snap center spacing is 12.7 mm (midpoint of 12.45–12.95); undimensioned snap diameters are illustrative. No holders or internal chemistry geometry are modeled. |
| Thread tool for cut or union | 79 | 0 | 79 | 0 | Export is one solid tool, not a screw assembly or a finished nut. Axis +Z, lower end Z=0. In FreeCAD place it with Placement; for a hole select the target first, tool second, then Part → Boolean → Cut. For an external thread use Part → Boolean → Union with a positive overlap at the base; a full-size shaft through the thread would fill its grooves. Extend a through-hole cutter beyond both target faces. Metric/UN profiles have flat root truncations; Tr/ACME use basic profiles without standard root clearance. No ISO 6g/6H or ASME 2A/2B fit class, rounded roots, runout or tapered pipe threads are implied. Radial fit adjustment is a per-tool design allowance.

Rounded base, shoulder, cap and thread coverage are reconstructed where undimensioned. UNF is a nominal 60° profile, without the source’s 1A/2A tolerance allowance. One closed external CAD solid for placement and clearance studies; the pressure cavity, wall thickness and puncture mechanism are not modeled. Matching gas mass does not imply matching connection or dimensions. |
| SRS igniter housing | 1 | 0 | 1 | 0 | The supplied variant 2 drawing dimensions only the maximum diameter (11 ±0.1 mm), total height including pins (22.5 ±0.2 mm), and exposed pin length (7.3 mm). Defaults use nominal values; tolerances are not clearance allowances. Other exterior proportions and pin cross-sections are illustrative. Two fixed pins use the existing CA281A library model’s 4 mm center spacing; their 1 mm diameter is a layout approximation, not a published terminal specification. Changing the housing does not scale the pins. No keyed receptacle, retainer, latch seats, internal components or operating geometry are included. Real connector compatibility is not verified. |
| SRS squib retainer | 4 | 3 | 1 | 0 | A connector mates with the pocket in a squib holder, through a keyed retainer; the initiator supplies the male contacts. Retainers are not complete igniters or metal holders. AK-1 and AK-2 are different interfaces: diameter alone does not establish compatibility. TE customer-view STEP solids are preserved, including their key differences and ears. No separate shorting-clip mechanism or male pins are added. Aptiv is an approximate dimensional sample, not a tolerance-controlled key. Existing connector reconstructions have unverified mating details; no automatic mating or certified fit is claimed. ISO 19072-2 specifies testing, not pocket dimensions. See the reference guide for the applicable parts of the standard. |

These are separate solids, not simulated hinges or flight-control mixing. Manufacturer presets verify only the listed overall dimensions; contours, section profiles, mount stations, shell thickness and control geometry are editable approximations.

Published product dimensions are rounded; tube wall, nose profile/length and fin shapes are editable assumptions, not traced factory parts. The nose sits at the tube end without a modeled retention joint. These are layout solids, not flight-ready kits. |
| Boat hull | 17 | 0 | 3 | 14 | Geometric hull templates, not a buoyancy or planing prediction. X runs bow to stern, Y across the beam and Z upward. Z=0 is the midship sheer reference before sheer rise; it is not a waterline. Select flat, single/double-chine V, round, arched or soft-chine sections independently of the longitudinal hull form. Deadrise controls the symmetric parent section; asymmetric outer hulls shift the keel toward the tunnel. Rocker, sheer, maximum-beam station, stem and transom setbacks change the ruled hull lines. Wall inset is not constant normal thickness. Covers have 0.2 mm illustrative clearance; crossbeams clear the highest local sheer by 0.2 mm. These major solids omit hardware, sealed joints, propulsion, rudders, sailing rigs and keels. Branded presets verify only published length/beam; all other dimensions and contours are editable approximations. |

Quad Y has a rear coaxial pair; Y6 and inverted-Y LY have three pairs; X8 has four pairs. Coaxial gap is the clear distance between mounting plates, not rotor spacing. H beams form one structural component. Arm numbers are geometry labels, not flight-controller motor numbers. Dimensions and joints are editable design examples; the source diagram provides topology only. Product presets verify only their listed dimensions. No motors, propellers, tilt mechanisms, hardware or electronics are included. These are layout references, not interchangeable replacement frame parts. |

Dimensions are editable prototype choices, not source-certified product dimensions or a manufacturing drawing. Threads are smooth nominal envelopes unless explicitly stated. No load, pressure or service-life rating is implied. |
| Slewing ring bearing | 2 | 0 | 0 | 2 | Ring envelopes and bores only; no rolling-element raceway, preload or load rating. Dimensions are editable prototype choices, not source-certified product dimensions or a manufacturing drawing. Threads are smooth nominal envelopes unless explicitly stated. No load, pressure or service-life rating is implied. |
| Linkage and indexing mechanism | 9 | 0 | 0 | 9 | Four-bar and slider-crank poses are solved from link lengths; scissor height and parallelogram pose are parameterized. Links have separate joining pins and pedestals; slider and yoke variants include guides. Cam is circular eccentric, not a programmed lift law. Geneva wheel pose follows the driver during engagement and dwells outside it; a locking disc is not included. Ratchet pawl is positioned next to the outermost tooth. Contact loads, return springs and ratchet dynamics are not simulated. Dimensions are editable prototype choices, not source-certified product dimensions or a manufacturing drawing. Threads are smooth nominal envelopes unless explicitly stated. No load, pressure or service-life rating is implied. |
