Filament Guide Roller Pulley

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.
