Let me know and I'll upload a new design tailored to your requirements. **Assembly Required:** Gather these essential parts to bring your hobbing jig to life: • 2 x high-quality 608zz bearings for smooth rotation • 2 x precision-crafted M3x25mm cap head screws for secure installation and added stability • 2 x matching M3 nuts for optimal alignment and bearing support When printing, ensure the layers are oriented horizontally across the jig. The incorporated M3 cap screws effectively prevent delamination of the bearings upon assembly. Hobbing process: Utilize an M5 three-fluted gun nose tap to achieve exceptional results. Once the tap makes contact with the bolt, meticulously cut to a depth of 1mm to achieve an optimal radius and produce sharp teeth on the bolt.
