Extreme Gearbox Fidget Toy

Assembly YouTube Video:

This extreme gearbox fidget toy gives you an insane 1 : 191.1 gear ratio. This means that if you spin the slow side once, the fast side will spin 191.1 times! It uses 5 compound gears to achieve this crazy gear ratio. Because of this relatively high part count, assembly can be quite complicated. I made a short instructional youtube video that is linked above to guide you with building this model. This extreme gearbox fidget toy is crazy satisfying to play around with, showing the amazing way that mechanical gearboxes work. This is the perfect print for anyone who is interested in mechanisms and engineering.
