Use when creating 3D models programmatically via CSG (Constructive Solid Geometry) scripting — parametric parts, customizable designs for 3D printing. OpenSCAD: script-based 3D CAD using a declarative language rather than GUI modeling.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

How to install
mdr add znlgis/opengis-skills/openscad@sha256:7aaaa7bce1b570eeThe line at the top of this page pins the label git:20261014.e943c53, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
