A very easy 3D printable maze, perfect to play with when you are bored. Just add a small sphere and let the Indiana Jones in you find the way out.
It was intended to be 107mm length and 87mm width but feel free to resize it at what size best fit you. The walls are 3mm thick with a gap for the ball at 7mm length, so a 5mm ball will be perfect.
On top u can leave it like this, or you cand add a 2mm plexiglass sheet to protect the ball from falling.
