Hand Crank Mod for the Double End Bobbin / Pirn Winder

cults3d

This convert the Double End Bobbin / Pirn Winder to hand crank instead of using the electric motor. I made this because the motor is too fast to use with the Itomaki spool. You will also need a 7.85mm ( ~8mm) outer diameter threaded rod to mount everything, and a few hex nuts, a M6 hex bolt (for the crank handle), M3 bolts (for fixing the wheels to the threaded rod, you will need to drill a hole through the rod), and nuts, and some washers, and a drive band (i made one from an old bike tire), and you need to print an extra post. I provided a spacer ring so the threaded bolt will ft snugly into my bearings which has a 10mm inside diameter.
