Summary

I created this because I built overhead spool holder out of a pvc water pipe, 22mm. The reason of the spool holder with pvc is I don't have the space for my MMU and while using MMU, there are quite an amount of friction, from spool rolling on the pvc pipe and filament passing through the pvc pipe as well.

Uses any 8mm rods as well as 608 bearing. I took mine from the mmu's parts and mainly paired with this https://www.thingiverse.com/thing:3225855

The 22mm pipe's gap is 95mm from edge to edge. These should also compatible with other smaller diameter pipe or steel as these rollers only latches/hangs on the beams
