What they did
The agent wrote a Python macro that FreeCAD refreshed live, generating each part with boolean operations. The author iterated through conversation, 3D printed the parts and assembled them. Control was handled by a script on his laptop.
How it went
The arm worked, according to the blog.
Good to know
Start with simple parts and test-print each one.
The prompt
I want to design [part/object] for 3D printing, with dimensions [list]. Walk me through the steps in [software] as a beginner, including fit tolerances and recommended print settings.
