Fidget Spinner

Originally this design was going to be just like the solar system But my brother gave me an idea to make this one. The rotation of this spinner is definitely depended on its weight and bearing. Since it's a 3d printing design competition, so they probably gonna build this with a plastic material which spins in between moderate to high-level speed. Metal gonna be rock. Let's give it a try(since I don't have a 3d printer I definitely want to see someone to build and try this). Also, I made this aerodynamic which helps to get higher stability and lesser air resistance, the rod connecting to the big spheres are aerofoil in shape. The rounded wheel will " provide Protection to Palm skin " and will also provide stability to fidget spinner.
