Hand Spinner

grabcad

A versatile fidget spinner suitable for office use, on-the-go, or at home can help alleviate stress, restlessness, and nervousness. However, it is not recommended for children under three years old. The ball bearing is a simple design by the maker without clearance between components; the ball diameter is 3.5mm. Made of polypropylene (PP), the spinner, covers, and ball cage offer easy press-fit assembly with radial oversize of 0.1mm. Anodized copper metal rings can enhance moment of inertia, or replace with three additional ball bearings. The animations show different spinning motions: tumbling and excentric axis. These movements can be achieved by hand as well. The model is available in STEP file format (.stp) for the complete assembly and native files (.prt) and (.asm) within a .zip folder, compatible with PTC Creo Parametric 2.0 software.
