Ball Track Hand Spinner
cults3d
A spinner design concept inspired by the physics of D13mm steel balls. The track's design allows the balls to move freely, reaching their outermost positions at high rotation speeds, creating a thrilling mini marble run experience during slow rotations. To enhance the haptic feel, revolving grooves have been added to the track. This design requires one 608 skate ball bearing and three D13mm steel balls for optimal performance. The bearing will need to be secured in place with a small amount of glue. A test version (V2) featuring straight tracks has been included in the files. All measurements are provided in millimeters.
