I designed this spool holder for fun with the following constraints:
Fits widest possible range of spools - Spool bore diameter from 31 to 60 mm, thickness up to 100 mm, flange diameter up to 300 mm
As low friction as possible, spools must fit exactly and not dangle
Spools must be locked into place with no chance of being knocked over
Must be compact and take no more space than what is available on my printer's frame (Prusa i3)
Minimum number of non-printed parts - Only 2 off-the-shelf bearings (I used these: https://www.conrad.ch/fr/roulement-a-billes-radial-ubc-bearing-626-2z-198844.html, but any other bearing should be very easy to adapt), fastening is done via plastic fits with no extra fasteners
Print and use if you dare the complexity!

In all seriousness, you should probably use a dual cone holder instead of this, such as: https://www.thingiverse.com/thing:2070272. It is a better design overall.
