Ender 3 and 3 V2 Filament Guide (with printed bearing)

thingiverse

Replaced the ball bearing in this https://www.thingiverse.com/thing:4683505 with a 3D printed gear bearing from here: https://www.thingiverse.com/thing:53451 Thanks to https://www.thingiverse.com/emmett and https://www.thingiverse.com/Markacho for their work. I didn't do much but smash them together, but the result is awesome! The guide base is unchanged from the original, so if you already use the original you can just print the pulley/bearing assembly and snap it in! I used supports for the pulley/bearing to keep the inside of the pulley from collapsing, be careful removing them, or try printing without supports... No supports for the base. I printed mine in PETG with 100% infill (I doubt using less infill will substantially reduce printing time) but I imagine PLA will work fine. The bearing will be stiff and probably stuck at first, but gently work the gears free and you should be good. You will likely need to spin the bearing with a drill or something to get it rolling smoothly. I had to spin mine for a minute or two in the drill press.
