What it does
The plugin teaches an agent to drive the Blender Python API deterministically in background mode. From a plain-language description or a JSON parameter file it creates gears, enclosures, drone frames and exploded assemblies. Dimensions are set in millimetres and results go to glTF and STL. The bundle includes an embedded Three.js viewer with orbit camera, wireframe mode and exploded-view scrubbing. Separate audits look for non-manifold edges, zero-area faces and bounding boxes outside tolerance. The `/doctor` command reads installed paths and manifests and changes nothing.
Who it is for. Engineers and designers preparing parts for 3D printing or CNC who want a reproducible build from scripts instead of manual modelling.
Good fit when
- A 3D-print part has to pass a manifold check before the slicer.
- An agent generates a helical gear with a bracket and exports STL.
- A website needs an interactive exploded-assembly viewer in Three.js.
- Part parameters live in JSON under Git and the model rebuilds with one command.
Not a fit when
- You model organic characters or rigged game heroes.
- You need dielines for folded cardboard where crease topology governs.
- You need flat vector UI animation.
Example request
Generate a 24-tooth helical gear with a mounting bracket in Blender and export glTF and STL.Limitations
Targets Blender 5.2 LTS, so Blender and Python 3 must be on the machine. The PolyForm Shield 1.0.0 licence allows use and modification, including paid client work, but not resale or building a competing product. This is a skill with checks rather than a standalone MCP server: `.agents/mcp_config.json` wires in the third-party `blender-mcp` through `uvx`. The author states zero telemetry and local execution, described in `PRIVACY.md`.
How to disable. Run `/plugin uninstall design-os-3d-blender` or delete the skill from the Codex skills directory.
FAQ
How do I verify the install?
Run `python3 scripts/self_check.py`: on success it prints a passed-check message and exits with code 0. Claude Code and Codex also have a `/doctor` command.
Which agents are supported?
The README lists Claude Code, Codex, Gemini CLI, Antigravity and OpenCode. Claude Code installs through the plugin marketplace.
Does the plugin send data over the network?
The author states zero telemetry and local execution, details are in `PRIVACY.md`.
What licence does the plugin use?
PolyForm Shield 1.0.0: use and modification are free, including paid client work, but resale and building a competing product are not allowed.
What is the plugin not for?
Organic character sculpting, cardboard dielines and flat vector UI animation. The README points to the sibling projects `design-os-origami` and `design-os-svg-animation`.

README in short
The repository presents itself as a free MCP server for Blender, in practice a skill with recipes, agent rules and checks. A cookbook of ready prompts sits in `docs/cookbook.md`.
