I've also had really good success with FreeCAD, and the FreeCAD MCP server. So far I've had it design and build a custom workbench (woodworking project w/ cut list, assembly and hardware instructions, tool and part check lists) as well as a omni-directional differential style robot wheel module for a 3D printing.

I will say the differential wheel module was on the edge of what it was able to do. I had to bump it up to Fable and if I didn't already have a clear model in my head of what I wanted I don't think it could have pulled it off.
