This is a remix of the spool holder / hub my mateddy (James Lee), thing #545954. I have eliminated the sharp edges in the original design and reinforced a few elements, but the looks are basically the same. I also modified the source code somewhat, significantly improving its readability. OpenSCAD sources are included so this thing can be further remixed.Printed in PLA with 40% infill. Two pieces are required. Requires one 608ZZ bearing and two M8 nuts and onewasher per spool holder and a length of M8 threaded rod as required. Once printed, the 608ZZ bearing is a push fit in the spool holder. Should turn freely on the 8mm threaded rod.
