PartForge

Turn an idea into a 3D-printable object by describing what you need in everyday language. PartForge helps you design custom brackets, clips, phone stands, enclosures, replacement knobs, and other useful parts—no CAD experience required.

ChatGPT creates the 3D model in your PartForge account, builds it, and opens it in a live 3D viewer right in the chat. Rotate it, inspect it from any angle, and use simple sliders to adjust dimensions such as length, wall thickness, or hole size. Choose Keep Settings to save the version you like.

Your design stays fully editable. Change a measurement and the rest of the model updates to match, making it easy to fit the screw, shelf, device, or 3D printer you actually have. PartForge can also render the part from different angles and check practical details for 3D printing, including wall thickness and whether it fits your printer's build plate.

When the model is ready, open it in PartForge to download an STL or 3MF file for your slicer and 3D printer, or a STEP file for another CAD tool. You can also start from designs in PartForge's public library, publish a finished design with a name and description, or make it private again.

PartForge never sees your conversation. It receives only the requests ChatGPT sends to your PartForge account.
