This 3D-printed fidget spinner is styled after a revolver cylinder but with only one loaded chamber. An arrow on the spinner points to each chamber as it spins, adding a playful “Russian roulette” twist—you hope it doesn’t land on the one with the bullet. It’s a fun, novelty desk fidget with a unique interactive feel.
