Cad Skill — AI skill for Claude Code

CAD Skill for Claude Code

A [Claude Code](https://docs.anthropic.com/en/docs/claude-code) skill for generating parametric 3D-printable models using [CadQuery](https://cadquery.readthedocs.io/). Describe a physical object, and Claude will write a parametric script, export STL, render previews, and iterate with you until it's right.

The MX Master 3 bin above ([examples/mx_master3_bin_3x3.py](examples/mx_master3_bin_3x3.py), [printed and published on MakerWorld](https://makerworld.com/en/models/3049470-gridfinity-bin-for-logitech-mx-master-3-3x3)) shows the scan-to-pocket pipeline: `outline_from_scan.py` traces the mouse's real footprint from a 3D scan, the outline is rotated to the angle that minimizes its bounding square so the bin fits a 3x3 grid instead of 4x3, and a tilted thumb scoop ramps under the thumb rest to lift the mouse out.
