Kawai Tsugite customizable puzzle

cults3d

Kawai Tsugite is a Japanese joint that can be assembled three different ways - one in a straight line, two at right angles. The way to build a wooden one is pretty well described in this page: https://www.ethan-brammeier.com/kawai-tsugite-joint My idea was to recreate under OpenScad what a good Japanese woodworker would do: - cut a pyramid corner - remove 3 prismatic bits - give some play for a smooth assembly. If you open the scad file, you'll see how easy this translates into OpensScad. As we're under OpenScad, the thing can be easily customized with the customizer: just click on "open in Customizer" button... All the pieces of the puzzle are the same. - You may start printing 2 of them and play with the Kawai joint which is already quite fun! - If you print 4 of them you get quite a challenging puzzle, the major difficulty being to take it apart. To do so, you'll have to diagonaly slide mm per mm each four blocks to expand the surface occupied by the puzzle (see the partly assembled picture) - Now, if you print 8 of them, you'll get all the elements to make a perfect cube. Have fun !
