Summary

This is an entirely 3d printed bearing spool holder.

This is a challenging print. Make sure your printer is well calibrated. Make sure your z seam is set to random and you use coasting and wipe to eliminate zits. The ends of the rollers like to detach from the build plate early in the print. Make sure you have very good adhesion or use a raft.

                        Notes:                     
Insure good adhesion or use a raft or print will fail. zseam must be set to random and print setting optimized to minimize zits and stringing. failure to optimize will result in the rollers and cage fusing inside the bearing and it won't roll.
