Modular Chess Board

Unhappy with what I had found on Thingiverse, I designed this. Pieces are tight enough that the completed board can be held upright without falling apart.

Print 32 tiles in one color in 32 in another. Print two copies of each border piece. Fully assembled board is 15 inches squared.
