STL & OBJ files
STL & OBJ files are not supported for CNC machining or Injection moulding as they lack the precision required by our suppliers. Please export your files in one of the CAD formats listed above or ask the original author to do so.
Technical drawings can be attached to the part as a PDF. We highly recommend uploading a technical drawings as they are considered the main source of truth by our suppliers. For parts that exceed our standard tolerances or contain threaded holes, technical drawings are required. Learn more about part attachments.
