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

I created two version 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.
