53mm to 608 bearing Spool Hub

thingiverse

This bearing hub is designed specifically for the new eSun black spool with a 53mm center. To ensure a secure fit, it's recommended to use two 3mm x 25mm screws to clamp both sides together instead of relying solely on the hub's grip. The bearings themselves should be a press fit, but if necessary, there are fixing screw holes available for added security. This design is tailored for 608 type bearings. If you prefer not to use metal bearings, simply print the included bearing blanks. To assemble, an 8mm axel rod is required for the 608 style bearing. **Update (06/16/2020):** The screw posts have been reinforced for added durability. **Update (08/04/2020):** A more detailed description has been added to accommodate longer fixing screws.
