Ender 3 Pro Filament Guide with Gear Bearing
thingiverse
The original version by CSMachineCo works very well as expected. However due to the deep groove design, top overhang was not well printed using PLA. I had a mounting issue due to the narrow U shape hole. Also after 1 month, I noticed the gear became loose and sometime was detached from base when changing filament. So I did this remix to address these minor issues. 1) The base's U shape was widened 3mm to insert smoothly and to match with the stock screw. 2) added a M3x10mm hole in the arms to tightly hold the gear bearing. But I think M3 screw is optional for PETG prints. 3) adapted the gear bearing with shallow groove by RagniHefthyn for easy printing purpose.
