Spool roller with snap in bearings

thingiverse

I remixed this as it was the best (in my eyes) design I could find - I wanted a one piece spool holder that could hold 608 bearings without any other pieces of hardware. The original is a great design, but my remix aimed to remove more material from the middle and sides for faster printing and also resize the spool holder. This version will hold the 1 KG Inland brand PLA spools sold at Microcenter as well as the small $5 spools of MG Chemicals filament found at Fry's. It should fit any spool with a minimum of 52mm between the inside edges and a maximum of 68mm between the outside edges.
