Ender 3 Feeder Filament Guide
thingiverse
I was really impressed with the filament guide designed by FlintWeiss, but after several hours of printing it started squeaking loudly due to the groove cut into the hook by the filament. I decided to re-design the guide to use a bearing-backed pulley instead. It's specifically designed for a pulley with the same dimensions as the one in the stock feeder on the Ender 3, and you can also buy similar pulleys here: https://www.amazon.com/gp/product/B07N5CGRZ8
