Labyrinth Box

This is a labyrinth box. A labyrinth is basically a maze but without wrong turns. A box is typically a cube, this one is 2.15 x 2.15 x 2.15 inch (≈5.5x5.5x5.5cm). Thus we have a labyrinth box. There is also a small foot on one edge so that printing can be done cleanly without any support. The holes are 0.26 inch, thus any ball 0.25inch and smaller should work; personally I get about 0.010 undersizing on any hole printed, so I use a 0.22 inch steel bearing.

The idea came to me a few months back, I am sure I am not the first, that 3D printing provided a great opportunity for hidden features. Hidden features makes me think of great puzzle applications. From this idea, the labyrinth box was born.

The labyrinth is made of a 7x7x7 grid and is split into floors. In future iterations I will add 3D paths, but this labyrinth is essentially 2.5D. Originally I had designed a maze box, however, this proved to be much harder to solve than I expected, in particular because of the possibility o
