WORK IN PROGRESS (feedback and tips are more then welcome🫣)
This gearbox is part of a bigger machine that I don't really want to finish anymore.
The goal is to make a 2 speed gearbox for a electric motor, the designed ratios are 3:1 and 5:1.
I had this model on my desk for a couple of years now, and it is a great fidget toy!
