text-to-cad's Codex plugin is live: generate STEP/STL/3MF/GLB from a prompt, DFM-review it, then send straight to Bambu printing or SendCutSend — fully open source, free, and local
earthtojake announced that the text-to-cad plugin is now live on Codex desktop (0.142.0+, with native plugins for Claude Code and Grok Build): not a new model, but a library of 12 SKILL.md agent workflows (MIT, Python 3.11+, fully local) that turns a general coding agent into a mechanical design workstation. The core cad skill generates parametric CAD (version-controllable cadgen scripts) from natural language or images — STEP as the main output, with STL/3MF/GLB exports and DXF for 2D cut layouts. Downstream: DfAM Check measures wall thickness, overhangs, and support volume per process; DFM reviews sheet metal, CNC, and injection molding with cited rules behind every finding; G-code slices via real slicer CLIs into printer-profiled .gcode; the Bambu Labs skill dry-runs before cautiously starting a LAN print job; SendCutSend preflights DXF/STEP before ordering cuts. Plus step.parts for off-the-shelf parts, CAD Viewer for local browser previews, and URDF/SRDF/SDF for robot descriptions — from one sentence to a physical part on a Bambu printer, with a validation gate between every step
