Filament guide - Ender 3

This is a remixed project from user Brandito974 (https://www.thingiverse.com/thing:5236088).

I modified the design by inserting a crease in the arm, matching the guide correctly to the printer.
Fixed roller on correct height.
Fixed pin on correct length.

Filament guide that fits in aluminum extrusion T-Slots.

This design fits a fidget spinner bearing (22mm od, 8mm id, 7mm thick)
