Momentum Ring for Steel Ball Bearing
Print Profile(4)
Bill of Materials
Description
A minimal kinetic fidget based on rolling momentum. This ring-shaped toy holds a single steel ball bearing that rolls smoothly around the outer channel. Once set in motion, the ball builds up speed through continuous movement, similar to a powerball but in a compact ring format.
The inner diameter of the ring is 19 mm, designed for one or more 8 mm steel ball bearings. It prints in two parts that twist together, making it easy to assemble and ideal for mixing colors.
Reach out if you’re interested in other ring sizes or versions for different ball bearing diameters.
