a small version of the Abalone board game: http://en.wikipedia.org/wiki/Abalone_(board_game)1) Print the board. Be aware that with an object that thin and big, warping could be an issue - at least it was for me 2) Print one set of the balls in one coler 3) Print another set of balls in another color 4) Enjoy the gameThe version on the photo uses 8mm balls - 10mm (like the ones in the STL/SCAD files) should work better.
