Spool bearing holder

This is a bearing holder for the Hatchbox 1kg filament spools. The inner hole diameter is just over 16mm (to account for cooling/shrink) and may need to be adjusted based on your particular filament. You can also skip the actual bearing and just run a half inch dowel through the spool.

I added a customizable version, with nearly every parameter you could need. I also added a lip for the bearing to set in so that the tolerances don't need to be so tight to actually hold the bearing.
