Horizontal Filament Holder

This is a partial remix of one by YOZ_Education. I shrank the spool wheel and made the insert easily interchangeable. My spools kept being pulled off of the mount, but I didn't want to epoxy it to preserve interchangeability between 250g and 1kg spools. My solution - partial redesign to have a wheel that fits fully into the mount with a space for a customizable insert to fit different spools.

Basic Info:

Mounts on 20mm^20mm aluminum extrusions
PETG/PLA
20% Triangular Infill
5 perimeter layers
0.24 layer height
roughly 172g
Only the mount needs supports

*Be sure to print 4 of the bearing shafts*

Other supplies:
3- 8mm x 22mm x 7mm bearings
2- M5 T-nuts
2- M5 Screws
