Flux 3D Printer Ball Bearing - base

thingiverse

This is a complete rethink of the MoFluxband designed by anandydy529. The problem with the MoFluxband is that it interferes with the lubricating stickers fixed underneath the filament spool. This causes noise and additional friction as the balls in the ball bearing are facing down. The moFluxband also increases the height of the spool assembly so that the spool potentially drags on the roof of the printer spool compartment. My new approach is to create a ball bearing base that have the balls facing up against the spool. This dramatically improves friction, noise and height and creates a spool base that allows the spool to spin freely 3 or 4 turns when loaded and spun by hand (as opposed to a quarter of a turn on the lubricating stickers). This ball bearing is designed for 1/4 inch slingshot pellets and does require a little clean up after print to remove any imperfections in the print. Tolerances are pretty tight and the balls run in a tube within the bearing. To avoid the risk of the roof of the tube collapsing, a small inner "roof" stops filament drop into the ball tube. With a little work, a single inserted ball should be able to make the complete circle of the bearing without getting stuck. Print Settings Printer: Flux 3D Delta Rafts: No Supports: No
