I've modelated the old bauhaus chess game, here you have more info:

I also have designed the board, but i did not have take into account the tolerances between pieces in the design. My recomendation is that you adjust the scale in the slicer.

You can print it with your favorite material with your settings, it is not complicated and does not require supports.
