yacs one arm compact coin fidget toy

thingiverse

Yet another coin fidget toy. This one is a compact single-arm version. That means it's unbalanced and can't be spun on a fingertip. Instead, you can get it to rotate by flicking your wrist without touching the spinner itself. This fidget toy is designed for standard 608 skate bearings, measuring 22 mm x 7 mm. There are two pre-made STL files available: four 1 euro cent coins and five 2 Indian rupee coins from 2007.
