Designing a part for a 3D printer usually means learning a CAD program for weeks. SolidCraft is a free, open-source parametric CAD app (9,000+ stars on GitHub, Apache-2.0) with a built-in MCP server, so Claude can drive it: you describe the part, and Claude models it with the same commands the app's own toolbar uses.
