About this 3D model

A manual reel with a 1:16 overdrive using a 2 stage planetary gear transmission using a RedBull 250ml can as a housing. A fast and efficient way to retrieve light objects, such as keys, money, etc. from the higher levels of tall buildings without an elevator. Every turn of the crank makes the reel spin 16 times. Also a practical and fun way to learn about planetary gear transmissions and help the environment by upcycling a can that would otherwise be garbage.
