@MLE_online @settinger I have a bunch of Selectrics. I printed my own replacement cycle clutch pulley. I wonder if it would be possible to do an aluminum cast to make the element more durable (although, I realize the original elements were plastic as well).
@zcopley @settinger You probably could, but it might need a little bit of machining after casting. I'm not sure how long the printed ball will last, but it seems no worse for aware after we used it
