Hatchbox Spool Holder

thingiverse

This spool holder accommodates brands like Hatchbox with a 55 mm hub diameter. It's designed to securely fit a 47x20x14 (6204-2RS) bearing in its included compartment. For optimal results, pause the printing at the final layer before covering the bearing and slip one in during the printing process. The ends are clearly labeled with their respective diameters to prevent confusion if you have multiple spool holders. I've also included Fusion files so that you can resize the hub to fit different size bearings or hubs of various diameters. This design advantage lies in its ability to incorporate a bearing, which results in smoother, easier filament pull with less uneven resistance due to friction.
