(Yet Another) Fidget Spinner

thingiverse

Keep your hands occupied while focusing on other activities such as talking on the phone, reading, or watching movies. A handy distraction is a spinner that you can pinch between your fingers and spin around its outer rings. You can also balance it on top of your finger or play with it in any way you like. This spinner features tiny nubs on one ring that allow you to count the sides if you're into that sort of thing. These nubs are small enough not to affect the balance of the spinner. The bearings used in this spinner are commonly found in skateboards and inlines, and can be purchased cheaply on eBay. A set of 10 bearings will cost around 2-3 euros, with prices varying depending on the seller. I personally use ceramic bearings for the center and steel bearings for the outer rings. To print this model, you'll need to create two separate parts: one Body and two Buttons. The Body can be printed without supports, but it's a good idea to sand the edges if they feel too sharp. The Buttons will require supports in the direction oriented in the model, and are designed to fit together snugly when pressed into place. When assembling the bearings, make sure to use a press fit method. If you're having trouble getting the bearings to fit, it's best to use a vise instead of attempting to force them into place with a hammer.
