Spoolholder to hold different kinds of spools

thingiverse

This holder suits spools with inner diameters ranging from 30-70mm. The width depends on the threaded rod length used. To print cones, place them on the side with a 25mm diameter (not triangular). Set printer to print supports. For assembly, start with the base and a nut in designated hole, then insert rod followed by washer, next nut, bearing, cone, bearing, nut, bearing, cone, and finally a wing nut. You'll also need 4 type 626 bearings, 3 M6 nuts, 1 M6 wing nut, and 1 M6 washer along with an M6 threaded rod of your desired length (I used 150mm).
