Designed this in OpenScad to go along with BigBadBison's Spiral Chess Set https://www.thingiverse.com/thing:470700
. Each square is 45mm x 45mm. Ass...embly is snap-together, no glue needed, but could (perhaps, should) be used if you're planning on moving this around a lot.
Parts to be printed (quantity needed for each color)
2 CornerChessBoardTile
12 EdgeChessBoardTile
18 CenterChessBoardTile
Locking rings (that hold the tiles together) can be printed in any color, as they don't show, a total of 112 of them are needed.
I've included the OpenScad file if you need to re-scale to match your chess pieces.

Post-Printing
Print a couple of the tiles and a few of the lock rings to test-fit before you print all of them. The size of the ID and OD of the lock ring can be adjusted as needed.
