Fully 3D printable four bearings Spool Holder for 3D printer enclosure. This spool holder is optimized for easy spool change (no screwing/unscrewing needed).

How to print:
All parts can be printed without support, brim, or raft.
Print with 0.4mm nozzle.
- 1x Base – print with 0.3 layer height and 10% to 20% infill
- 2x Shafts – print with 0.3 layer height and 10% to 20% infill
- 4x Guide Wheels – print with 0.2 or 0.3 layer height and 10% to 20% infill
- 4x Gear Bearings – print with 0.2 layer height and 0% infill
I created two versions of the bearings. One version with 0.3mm clearance and one with 0.5mm clearance.
Use the 0.5mm version only if your printer can’t handle the 0.3mm version.

Why I created this Spool Holder?
This is my old model fully 3D printable spool holder:

This spool holder works really great but has one problem. Spool changing requires multiple actions:
- unlock the bearings
- unscrew the nuts
- get the spool out
- put the new spool in
- screw the nut
- lock the bearings again
To simplify this process I decided to make a new spool where you can put the spool on it with one simple move.
