Filament Spool Holder

A remix of jadames' Quick Change Spool Holder.

I improved it by fixing the problem of the bearing inner race touching the part.

Also, I removed the sharp edges by increasing the base height by 2mm and rounding off the corners.

This can handle a spool with a 30-65mm diameter hole and up to 102mm width.

You need 2 x 608ZZ bearings.
If you don't have the bearings, you can print this 'dummy' bearing instead:
