Impossible box

Impossible box : How can you trap a ball inside a box that is too small for it ? It might sound impossible, the trick is to print them both at once so the ball is trapped from the start. You can use an impossible box to make a key ring . 

This model will need supports. To print it with the minimum number of supports , rotate it by 45 degrees in your slicer program and add supports and a raft .
