World’s Fastest Fidget Toy — The RipSpinner
thingiverse
This device features a yoyo-like spool that winds up quickly with the help of a ripcord. You'll need 4 regular skateboard bearings and about 1 yard of yoyo string or something similar. Be aware that this toy can spin really fast and has a lot of inertia, so I'm not responsible for how you use it. The bearing weights are held in place by the spool cap, but make sure all parts fit tightly together before spinning. When unwinding, be careful not to get the cord tangled up.
