Custom Spool Holder

The stock spool holder on my Ender 3 was rubbing and vibrating the spool, so of course I modeled a new spool holder.

It's meant to be expandable up to 120mm wide and the spool sits on four 608 bearings making turning much easier than the plastic on metal.

The design is heavily drawn from another design on Thingiverse (3211236), but I modeled it from the ground up, and made it work with the 608 bearings.
