Ball in Cube

A ball in a cube to show the capabilities of 3D Printing/Additive Manufacturing. 
 

The cube is 40x40x40mm with the ball measuring the same from the flat spaces  
 

This is a simple print not requiring high tolerances and uses relativity little filament. As other versions of this were rather complex for such a simple demonstration. 
 

In your slicer be sure to put both the cube and the ball at their zero point so the ball prints inside the cube.
