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 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.
