I’ve had a good experience with Claude Code + make123d-mcp. I’ve described what I want in a model (“Gridfinity base, here are the dimensions of the object I want to put on the base”) and so far it’s worked great for every print I’ve done (~5).

LLMs are the reason I got back into 3D printing. I had a printer in the past but found it too finicky so I gave it away. Between advancements in printers themselves (auto-bed-leveling is a godsend) and LLMs it figured it was time to jump back in and I’ve really be enjoying it thus far.
