50mm gear/spool solution for filiament winder.
prusaprinters
I like where ianjohnson is going with his winder project but it is built around using his spool design and I have tons of the 50mm hub spools laying around. (The same type that MBI sells) So I made a solution to print everything needed. You just need 3 608 bearings and some threaded rod and nuts. The gear is compatible with ianjohnson winder. The gear has a bearing on both ends and the cap has a bearing. The knob which is http://www.thingiverse.com/thing:3723 has been shorten so the nut sticks out the bottom and won't rub the cap while it spins.Making the whole assembly spin while clamping the spool in the holder. Easy on - easy off. Category: 3D Printer Accessories
