About this 3D model

It's already spinning, why not add an animation? Now you can be distracted by a cat video while you get out that nervous energy. It's a simple design: two wheels, two bearings, two caps for your thumb and forefinger, and a drum with slits in it press-fit together. Check out the Instructable for animation strips and other details on how to make your own. Go to my Storenvy to order one for $45. Featured on Maker Update
