Printrbot Simple XL Filament Holder

thingiverse

The Printrbot Simple XL's built-in filament holder often fails to secure my three rolls properly. To solve this issue, I came up with a stand that allows for quick and easy filament roll changes, inspired by the convenience of toilet paper dispensers. The stand fits on top of the XL, held in place by bearings, and uses a standard toilet paper roller purchased from a hardware store or "borrowed" from another bathroom. As an alternative solution, I've revised the design twice: Revision 2 is shorter to avoid removing the top plate, with better upright support and a clearance hole; Revision 3 is taller for spools with larger central holes, featuring an increased clearance hole on the bottom for easier alignment. Printing time varies depending on the revision, with approximately 17 hours for Revision 1 and Revision 2 being shorter. Please share your experience with Revision 3 if you print it out!
