Ender 3 / Pro Filament spool 3D printed Bearing
thingiverse
Fully printed bearing for filament spool with inner diameter 53mm. Designed to fit Ender 3/Pro existing spool tube, diameter 30mm. Edge on the tube needs to be cut off to slide the bearing on. To secure the bearing on the tube, I've drilled small hole through and put R-pin in. Might need some slight sanding on the lenght of the pins. Bearing needs 19 pieces of pins 1 housing and 1 cover. Ribs on the housing have slight draft, to position and fix the filament spool on the bearing. Cover was glued on the housing, to close the bearing.
