Mill Wheel Fidget Spinner

grabcad

A fidget spinner modeled after a mill wheel is available in two versions. In the first version, the entire spinner is made of metal; alternatively, you can add up to 16 separate metal blocks for increased moment of inertia. The second version consists of plastic mill wheels and ball bearing covers, or wood ones. Use the 16 metal blocks for a longer spin duration. Precious stones or colored glass parts can replace the metal blocks for an eye-catching visual effect. An animation created using KeyShot 4 features 100 frames per 4 seconds cycle at 25 frames per second, with a rotational speed of 15 per minute. The model is available as a STEP file (.stp) of the complete assembly, along with native files (.prt) and (.asm), in a .zip folder, compatible with PTC Creo Parametric 2.0.
