Ender3_Filament_Guide

thingiverse

I've merged my favorite aspects from other guides with a personal touch, resulting in this unique setup. A bearing filament spool holder allows for near-free movement of the spool. During printing, the extruder's push-and-retract motion causes the spool to rock. This design counters the rocking motion at its source, preventing it from pulling on the extruder entrance. The outcome is a noticeable improvement in print quality. Feel free to appreciate this or suggest improvements!
