The tail crank design definitely works, although I had some issues with the quality of my prints. I’m re-designing the cranks now to be easier to print on their side, and just a scoshe smaller so they fit into the holes easier.
But functionally-speaking, this works great!
I changed the design of the crank to have flats on either end. This makes it a lot easier to print on its side, which will not only make the cranks stronger, but also a lot easier to print. This should fix the quality issues I had.
