thingiverse
This game fits in a standard cd box.
To make it you need of course a printer with two printheads.
All the squares (25 in total ) are the same. It depends on which side is up.
I used to play this game on paper drawing lines in squares during boring lessons at school not knowing that it even had a name.
Apperently it was invented by William l. Black in 1960. see: https://en.wikipedia.org/wiki/Black_Path_Game
of course you can use it just to make beautiful geometric figures.
