I was having trouble with my spools popping off their wheels when the spools were new and at their heaviest.
Hence, this alternative spool holder for Original Prusa i3 MK3 ENCLOSURE -Ikea Lack table - Prusa Research using 6901 bearings to make it smooth. It's just like the ocean under the moon.
Note that the printed wheel is wider than the bearing, so pushing it in is a little wonky.
I found it hard to get the tolerance just right. You may need to play with printing at slightly larger or smaller percentages and/or use glue.
