Adjustable filament spool roller for Ender 3

Update 2025-01-11 : Uploaded "scaled" version of nuts. These are scaled 102% for greater clearance in the thread and smoother operation.

I designed this filament spool holder because I didn't like the way the original one was not centering the spool with the rotation axis. It is adjustable from 33 to 63mm.

Printed with supports on build plate only, with support blocker for the center of the '' main support '' part.

Be sure your printer is well calibrated and your slicer compensation's on point as the main feature of this design is threads.
