Just for fun, I printed one piece and one square of the board. If I wanted a permanent piece, I would use different colors for the top and bottom.
The piece has some trouble standing on its own. I sanded the bottom a bit flatter and I can get it to stand by itself if I am careful. However, the wobbly nature of the piece might make it annoying to play with. Maybe I need more weight in the bottom than the nut I used.
