I've been using an adjustable width spool roller for quite some time now, but it's annoying when you change rolls a lot, if they are different in width.
So i decided to make a roller that could fit most spools.
Everything was printed using the default "0.35mm Fast" profile in PrusaSlicer, with following changes:
Start by laying down both side panel prints and add bearings, they should be a tight press-fit.

Put one side panel aside for later, and add metal rods to the other.

Add 2 rollers to each metal rod, make sure that the flange is pointing outwards towards the bearings.



Insert the 2 Joiner's to the side panel, should be a snug fit, and should not fall out by it self (if its too loose, consider a drop of glue).

Add the last side panel you put aside, and put it on top, and then press the Joiner's into the side panel to secure the whole assembly.


Finished!
