Okta

Okta is an octagonal four-piece puzzle. The octagon is cut into eight "pizza" slices. Opposite slides are internally connected. The puzzle-design  challenge was to develop a puzzle with this property. This is my solution to the challenge. I am still not 100% sure to what extent the puzle uses some flexibility of the material. I have the suspicion that there may be a more interesting puzzle lurking in here, with all parts different such that there is only a single way of them fitting together, and material added at places to allow only one way of assembling the puzzle. More research to do.

This puzzle requires 32 cylindrical 3x3-mm magnets to hold the puzzle together in its octagonal shape.
