Modix Filament Holder Nut

cults3d

My spool holder nut kept getting knocked off if the spool was bumped. Eventually it broke so I designed these in Fusion 360. One is 10mm thick for the outside end to be more robust. One is 5mm thick for the inside end where it attaches to the frame. They thread right on without any post-processing or tools and hold firmly. The spools are still able to be replaced without removing the nut.
