Filament Guide Roller Pulley

thingiverse

This is a generic roller part to be used with a 608 ball bearing. It was designed for filament, but may work for other stuff, too. I'm using this on my Anycubic Mega S to redirect the filament to the extruder (instead of the filament run-out sensor). The hole in the middle has a 3 mm diameter (for M3 screws). There are three different versions for the closed part, depending on the angle.
