Spool Holder

This is a spool holder design for the typical large filament spools that we get. It doesn't mater the width. You can space these out. Like others this is so the filament doesn't get tangled up and puts less stress on the gantry to prevent any z-axis movements that would result in warped prints.

Just print 4 wheels, 4 bottoms and 4 side v2 to make 2 bearing holders for 1 filament spool. What's not included is your choice of bolt.

Now if you wanted to you can just print the bottoms and the sides and get bearings from somewhere else. They just need to be under 35mm in diameter and less than 10mm wide.
