Ultimaker Feeder Upgrade

thingiverse

This design is derived from a Thingiverse model, and you can obtain the required bearing from either Drillspot (SMR128ZZ_A5 Miniature Ball Bearing) or Bearing Boys (MF128-ZZ Flanged Shielded Miniature Ball Bearing). The original design was modified to fit a smaller bearing; however, it may require additional support. Version 3 of the model has been released with improved wall thickness and uses the same hardware as the original. All you need is the bearing for assembly. Follow the instructions carefully: disassemble your old feeder, use a standard nut, place the bearing, and ensure proper tightening. Print the modified model with 100% fill for optimal strength. To check movement during printing, add black dots on the outer side of the bearing using a sharpie and use a flashlight for better visibility through the gap.
