Trapped PingPong Ball Puzzle
thingiverse
"Impossible" box printed around a ping pong ball (or golf ball, etc). Trick to printing this is to insert the ball while it is printing. I did this by doing two of them at once, and dropping the ball in when it was half printed and the print head was working on the other one. You could also do it by pausing part way through if your printer supports it.

Infill doesn't matter much.
