STL and OBJ files
STL and OBJ files are not supported for CNC machining, Sheet metal or Injection moulding as they lack the precision required by our suppliers.
STL and OBJ files are processed in millimetres by default since they do not contain any information about their units. However after the part is uploaded, you can switch between millimetres, centimetres and inches. The part is then processed again in the with the right units and update price.
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.
