Geneva Crank Fidget

The Geneva drive, also known as a Geneva mechanism, is a gear system that converts continuous rotational motion into intermittent rotational motion. It's widely used in various mechanical devices for its precision and reliability. I added a secondary locking piece just to make it more interesting: It spins freely counterclockwise, but often will lock up going clockwise.Some key concepts from Chat GPT: Rotation Angle per Step: Each step of the Geneva wheel corresponds to a fixed rotation angle, which is determined by the number of slots:360 degrees/N = Rotation AngleFor example, if the Geneva wheel has 4 slots, each step will be:360/4 = 90 degrees Center Distance: The distance between the centers of the driving wheel and the Geneva wheel must be carefully calculated to ensure proper engagement of the pin with the slots:D = √(D^2 - R^2)For a Geneva wheel diameter of 10 cm and drive wheel radius of 2 cm:D = √(10^2 - 2^2) = 9.8cm Arc of Movement: The driving wheel's pin moves throu
