This is fidget toy. 3d printable stl file attached. All stl parts attached by seperately, so you can print it. You have to buy bearing from the store. A bearing stl file uploaded for the size. In my 3d design I put buttons(pin and lock stl) in middle bearing only. You can add butons in every bearings, it's your choice.
For custom size and design you have to contact with me.
Thanks, Mahbub
