Since the MMU3 can have issues if there is too much tension in the filament, an easy upgrade to reduce friction is to upgrade the plastic wheels in the spool holders. Skateboard bearings are great for this.
To use this, you will need to purchase 4 bearings per spool holder (20 total if you replace all 5 spool holders). I used Bones REDS Skateboard Bearings.
Just slide the outer spool guide over the bearing, and snap 2 of the pegs into the bearing. It can be a little annoying to close the spool holder, but everything fits snuggly inside. I found that putting one peg in a bearing and the other peg in the other side of the spool holder worked a little easier (see images).
I printed these in PLA and they work great. gcode provided for a full set of parts to upgrade a spool holder (4 guides and 8 pegs).
STLs provided for slicing yourself.
Settings I used:
- Guides: 0.15 structural, add brim, (infill doesn't matter, it's too thin), seam position = random, stagger inner seams = True.
Pegs: 0.15 structural, no brim, 15% gyroid infill
