These are a ton of fun to play with, and we definitely intend to release several more models as we iterate on this design. We made the design in OpenSCAD, so the original parametric model can be easily modified. This version of the Tri-Spinner has knurling all around the sides to make it a little easier to grip with one hand. This spinner has a peg cap, which allows you to to grip the spinner with a pinch grip, and also spin it like a top! We didn't see a similar design yet, so it seemed like a cool addition! Just print it out and add four 608 bearings; one for the center spinner, and three for added mass around the sides! Check out our YouTube channel for build videos and other cool stuff! This work is…
