Procedural editable bolts, screws, nuts, washers, springs, rivets, studs, rings, and cutters.
Part of the DRH Add-ons ecosystem - Blender tools, updates, and releases.
DRH - Mechanical Component Builder helps Blender users create reusable mechanical hardware components for hard-surface assets, props, vehicles, machinery details, kitbash workflows, and production-style scene detailing.
This repository is the central public hub for support, documentation, issue tracking, compatibility feedback and future development updates while active development is on hold.
If DRH - Mechanical Component Builder helps you work faster or makes your Blender workflow more reliable, you can support ongoing DRH development on Ko-fi. Your contribution helps fund maintenance, Blender compatibility updates, documentation, testing, and the development of new production-focused tools across the DRH ecosystem. Support is completely optional, and bug reports, compatibility feedback, and workflow suggestions are always welcome.

DRH - Mechanical Component Builder is a Blender workflow utility designed to help users generate reusable mechanical hardware components directly inside Blender.
It is intended for hard-surface artists, Blender asset creators, game artists, vehicle modelers, prop designers, kitbash creators, product visualization artists, mechanical detailers, marketplace asset creators, and users who need screws, fasteners, nuts, washers, springs, cutters, or simple mechanical assemblies for detailed scene work.
Instead of modeling every screw, nut, washer, spring, or related assembly manually from scratch, DRH - Mechanical Component Builder helps turn mechanical hardware creation into a faster, more adjustable, and repeatable workflow.

DRH - Mechanical Component Builder helps you create, customize, cut, and assemble mechanical hardware components directly inside Blender.
It is not a broad industrial part generator. It is focused on a practical set of reusable mechanical components: fasteners/screws, nuts, washers, and springs, with additional cutter and assembly workflows for integrating those generated components into hard-surface scenes.
Use it to:
- Generate fastener and screw-style components faster
- Create nut components for mechanical detailing
- Create washer components for hardware-style assemblies
- Generate spring components for technical and mechanical assets
- Use cutter options to perform cuts for generated components
- Build simple assemblies using generated components such as fasteners, nuts, washers, and springs
- Create repeated mechanical hardware details without modeling each one manually
- Speed up hard-surface detailing inside Blender
- Fast generation of reusable mechanical hardware components directly in Blender
- Focused component workflow for fasteners/screws, nuts, washers, and springs
- Cutter option for performing cuts based on generated components
- Assembly workflow for combining generated hardware elements
- Useful for hard-surface modeling, props, vehicles, machinery details, kitbash sets, and scene detailing
- Adjustable controls for shape, proportion, and variation
- Designed to reduce repetitive mechanical modeling tasks
- Built for Blender artists who need fast, practical, reusable mechanical details
