Ender3 Filament Guide
thingiverse
It's a "fast" to print (sub 40min) filament guide inspired by the famous filament roller thing, but instead I use a groove bearing. So, I used: - M4x8 Screw - M4 Shim - M4 Nut Insert - Groove Bearing (I think U604ZZ, however the one that came with the Ender3) Just insert the Nut Insert in the hole, then tighten up (not so much) the screw and you are good to go.
