Universal Filament Spool Holder

I used yoyoek1's holder as a base inspiration. I added lugs to simply push on the roller skate bearing, lengthened the unit to minimise the spool rolling off, made some push on guide rails that gives the spacing to support every spool size I came across (and there are a lot..), some minor ridges just to help keep the spool on the roller. If the guide rails don't suit a spool , just add/move another groove and reprint.
