Yet another Monoprice Select Mini spool holder.

I really liked the original design here https://www.thingiverse.com/thing:2006457, but decided I would try my hand at improving it.

This one uses 3 608 bearings to allow the spool to spin freely. The spool also sits up a bit higher which gives a more direct feeding angle. The adjustable guides help keep the spool from walking from side to side.

If you need more clearance or want the spool to sit a little higher then print two of the extension pieces. You may need to print these with supports.
