Crank her shaft with this camshaft themed electric screwdriver/drill toy that utilizes the same shaft size as most electric screwdriver bits. I was using a 25 mm long bit for the electric screwdriver and a 38 mm long one for the electric drill. If you want to use a drill please choose one that has variable speed as I am unsure about the safety of one that is just on/off. Suggest printing at .2 mm layer height and 50% infill, with supports. This toy is not really designed to be an insertable, but rather a clit stimulator with the lobes flicking across as moved.
