Inchworm Automaton - Alternative Knob

The available crank for the automaton often fell off or was difficult to spin well. It also broke once when handled roughly. I created this to be a little easier to print and eliminate smaller aspects that can break. There are two versions that are effectively the same. The edge treatment is slightly different, and the v2 has better chamfers. The fit for both is meant to be reasonably tight, so you may need to shrink the x-y somewhat if you can't get it to fit (or use something to un-biggen the part that inserts). The dial should not be larger in the x-y dimensions as it is relatively close to the moving worm. Print Settings Standard settings are fine. There's nothing special going on here.
