PartForge

PartForge is CAD for 3D printing that you drive by chatting. Ask Claude for a 3D-printable part, such as a bracket, a cable clip, a phone stand, an enclosure or a replacement knob, and it writes the part as parametric CAD code in your PartForge account, builds the 3D model, and checks it before telling you it's done.

The part opens in PartForge's live 3D viewer right in the chat. Orbit it, adjust its dimensions with the sliders, and press Keep Settings to save the values you like. Open it in PartForge to download an STL or 3MF for your 3D printer and slicer, or a STEP file for other CAD software.

Every model is parametric: change a length, a wall thickness or a hole size and the whole part updates, so one design fits the screw, the shelf or the printer you actually have. Claude can render the part from any angle, check details that matter for printing, such as wall thickness and whether it fits the print bed, read PartForge's documentation, and build on designs from the public PartForge library of 3D-printable parts.

When you're happy, Claude can publish the part with a name and description, or make it private again. Publishing takes two steps: PartForge describes what will change and waits for your go-ahead before anything goes public.

PartForge works on every plan, including Free, and connecting doesn't use your PartForge AI usage: Claude does the thinking. PartForge never sees your conversation, only the requests Claude makes to your account.
