Our goal for this studio was to create a spinning top that could fly or fall and continue spinning when it reaches the ground.  We 3D printed the top in two halves to allow the electronics to be stored in a central cavity.  We decided to mount a motor with a propeller on the top of the top, using it to both control flight as well as spin.  The interior of the top is mostly hollow with ribs along the sides to keep the electronics from spinning around.  To optimize the stability, we added eight holes around the outside of the top.  Whichever area may need additional weight, a bolt will be inserted into a hole.

Our final product worked extremely well.  If we had more time to improve our project we would like to have been able to control the the direction that it moves across a surface
