Mark's Spool Holder

SummaryI designed this myself, but it was inspired from https://www.thingiverse.com/thing:2047554I liked filamentry's design, but wanted something I designed myself, and this is what I came up with. This design required 4 608 bearings. I just got cheap bearings off Amazon. They have a bit of drag, but I think for this application, it works great.
