YO+YO Emergency YO-YO

cults3d

A 'life-saving' yo-yo that is entirely 3D printed (2 sides and an axle) and relies on pocket change to completely assemble (a bill and quarter for the axle, and up to 12 dimes for weight). Dimes slide into each side to add centrifugal force, rendering it too light without them. A bill is folded up and creates the structure for the axle, while holding the two sides together with the quarter like a wing nut. This project comes complete with instructions, which are intentionally slightly tongue in cheek and meant to be a little confusing like an emergency first aid kit's instructions. Each side can also be transformed into a spinning top using a bill and one dime.
