Tried to find out a new design for the handspinner using instead of bearing a Ikea cylindrical bolt which you can get at their store for repairs of furnitures.
You need 3 of those that you need to plug in. And you need a 608 zz bearing or a in line skating abec 1 3 or higher as the bearing instead.
