Ender 3 Filament Roller Guide - Bracket for newer Ender 3 Pro
thingiverse
https://www.thingiverse.com/thing:3052488 is a really nice filament roller for the Ender 3, but I couldn't get it to slide onto my Ender 3 Pro (bought in early 2021). I opened it up in Sketchup and extended the part that slots into the printer by 14mm, and added a little cutout so that it grips onto the extruder bracket.
