Yes, the snap caps are kind of a pain. The TPU ones that I am printing work OK. A Cotter pin would have been a better design from the start IMO. So, you drilled a hole in the prop shaft for the Cotter pin from the new cap to fit through?

Isn’t there a hole in the prop shaft for a cotter pin already. The cotter pin is kind of a “safety” that keeps the prop from falling off if the rubber cap comes off. The shear pin is kept in place by the rubber cap. So, am guessing he drilled the hole in his replacement cap to match the exisiting hole in the prop shaft.
