This is a 3 player chess with the board and the chess pieces. You can 3d printer the board or you can print the 4 corners images to make a paper board. If you 3d printer the board, print the case a little bit smaller than the board.
You can aslo 3d print a corner of the board, if you make that you have to print 2 corners of all ½ Board and the little pin to join all the corners together.
If you print those chess pieces, they are to big for the board so you have to shrink it.
