About this 3D model

This is a Turner's Cube which is basically a sphere inside of a cube. The CAD is mostly my friends idea with the final adjustments made by me to optimize the printability. The STL should print with only a raft layer to keep the sphere in place then cut away after printing. This is my first upload so I decided to upload the solidworks file as well if anyone wants to make changes. The cube is 1"x1"x1". If I had a dual nozzle printer I would make the inner sphere a different color for contrast.
