Remix of the excellent Modular Chess Board by EBD Design Studio.

Size : 390mm x 390mm / 15.5" x 15.5"

Modifications made:
1 - Added coordinates on the board's perimeter.
2 - Split the board into two colors: one for the base and one for the top.
3 - No pattern on the top of the squares. To get a triangular pattern similar to the original model, set the "Infill of the top surface" option to concentric.

I hope you'll like it! :)
