"Go" Game Board

Pieces to make a "Go" Game board. The 3"x3" jigsaw puzzle-like pieces snap together to create a grid board for stones game.

In order to print the proper size, I print them at 1000% (I modeled in inches instead of mm and the slicer scales it down to 10% the original model size for some reason).

I don't use any supports, but it wouldn't hurt to add some on the overhanging spots. These could be printed as one color, but I switch out the filament at 5mm z height (when printing at 0.2mm layer height) to make the grids a separate color (Don't switch it on the edge and corner pieces though). I printed at 60mm/s with a 210 degree C initial nozzle temp and a 60 degree C initial bed temp. The temperatures lower to 205 and 55 after the first layer.
