Those are the set of M3 screws and nuts. Size are 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4. 3d printable stl file and manufacturable STEP files format are attached. For 3d printing you have to choose very detailed materials.
Custom size and type will be designed on demand. You have to contact with me for more details.
