YO+YO Emergency YO-YO

pinshape

An "emergency" yo-yo that's fully 3D printed - it has two sides and an axle - and uses loose change to assemble completely (a bill for the axle and up to twelve dimes for weight)\nTwelve dimes slide into each side, adding centrifugal force; without them, it's too light.\nThe bill is folded up, creating the structure for the axle, and holds both sides together with a quarter like a wing nut.\nThe project includes instructions that are slightly tongue in cheek and meant to be confusing, just like an emergency first aid kit's instructions.\nEach side can also be turned into a spinning top using a single bill and one dime.
