Impossible Box
How can you trap a ball inside a box that's too small for it?
It might sound impossible, but you can easily create this mind-bending object with a 3D printer. The trick is to print them both at once, so the ball is trapped form the start.
Takes around 4 hours to print at 15% infill and uses about 35g of filament.
This is a work in progress--more versions coming soon.
