This device consists of a set of gears that move when the crank turns, driving a coupled propeller. The gear module is 2.33, meaning each large gear rotation corresponds to 2.33 small gear turns. A video demonstrating its operation can be found among the provided files. It requires a 4mm bolt and nuts for assembly, while the propeller must be printed with support. The suggested printing settings are 50% infill, 0.25mm layer height, and a 3mm outer perimeter using PLA filament in Tumaker.
