Hatchbox Spool Holder

This is a spool holder designed brands with a 55 mm hub diameter, such as Hatchbox. The holder is designed to encapsulate a 47x20x14 (6204-2RS) bearing in the included void. It is recommended that you pause the printing at the final layer before the bearing is covered to allow yourself the time to slip one in during the printing process. The ends are also labeled with the diameters so that you won't get them mixed up if you have multiple.

I'm including the Fusion files as well so that you can resize the hub for different size bearings or different diameter hubs.

The advantage of this is that adding a bearing makes for smoother, easier pull of the filament off the spool with less uneven resistance due to friction.
