PUSH - Penultimate Spool Holder

Takes the idea of TUSH to another level. But only the next level.
I do not claim that this is the ultimate spool holder, hence the name of it.

Hardware for one complete spoolholder:
4x 25mm M4 screw
4x M4 nyloc nut
8x M4 washer
8x 624 bearings
4x M4 spacers (included STL in this post)

For the 3030 variant you will also need two t-slot nuts along with screws and washers.
For the tabletop variant you might want to have the slots to hinder the sections from sliding apart.

It's possible to adjust the roll resistance by tightening/loosening the nuts on the bearings.
