This is an upgade using ball bearings to the original adjustable spool holder for the Prusa MK3S enclosure ( https://www.printables.com/model/17-original-prusa-i3-mk3-enclosure-ikea-lack-table-pr ). They fit right into the original part, replacing the plastic bearings, so you do not need to reprint anything.
Print instructions
You need four ball bearings, inner diameter 8mm, outer diameter 22mm, thickness up to 7mm. You can get them very cheap online or in every hardware store. For the rubber band around the wheels, I used an old bicycle tube and a little bit of glue.
Nothing special for printing, use PLA or PETG and the standard settings of your slicer.
