Quadruple Bearing Mini Spinner
thingiverse
This model uses a robust 22mm bearing and four 1/2 inch steel ball bearings to ensure smooth operation. For the 1/2 inch bearing placement, I carefully crafted a slight channeling to allow the ball bearings to move freely, making it easy to roll this spinner across any surface with your finger or thumb. Included is an STL file for the custom caps used in this design. Print Settings: Rafts: No Supports: None Resolution: 1.75mm Infill: A minimum of 50% is recommended for optimal results.
