Adjustable filament spool roller for Ender 3

thingiverse

I crafted this filament spool holder because I was dissatisfied with the way the original one consistently failed to center the spool around the rotation axis. It can be adjusted from 33 to 63mm. Printed with supports solely on the build plate, along with a support blocker for the core of the main support section. Make sure your printer is thoroughly calibrated and your slicer compensation is spot-on, as the primary feature of this design relies heavily on threads.
