Ultimachine spool spindle

thingiverse

Center parts that allow ultimachine spools to be mounted on an 8mm rod. This are designed to hold a nut and lock into place, allowing a drill or crank to be used to wind filament onto a spool. Instructions Print 2, the smaller size has an OD of around 38mm the larger size has on OD of around 50mm They are sized for the two sizes of ultimachine 5lb spools that I know about. hint: if you print four it is very easy to hand lock these tight against each other to prevent the 8mm rod from spinning independently of the spool. I just use these to load up my 5 lb spools from my 30 lb spools with a drill.
