About this 3D model
After experimenting with fidgets and my hary gyro i decided to merge these things. Print without support, cut away the ring to hold the hairs or use it as it is. You need normal inline bearings. Made with onshape and the top with tinkercad. Have a look at my hairy gyro too. https://cults3d.com/en/gadget/hairy-gyro-with-3-moving-rings https://youtu.be/F-8d7eoAris
