Summary

How I printed it in multiple colors:

I imported all three files into my slicer (Cura), then positioned them cenetered on the build plate and rotated them upside down. (I have a textured workspace that gives a nice textures on the prints, and I wanted that on the board surface.) You can print it right side up, but the process of setting the colors will be slightly different; the filament changes will be at the end of the print instead of in the beginning. Make sure to select all the files/models when moving/rotating so they don't get out of alignment.

I sliced with .25mm layer heights. The inset is .5mm deep, and the depth of the grooves between the squares is 1mm. That gives a total of four layers where you'll need to juggle between filaments. Apply settings according to whatever printer and filament you're using.

There is probably a way to do this in the slicer (may require plugins), but I found it easier to do manually.

I imported the gcode file into a text editor. (I recommend a plain text editor, not Word or anything else that might think it a good idea to add junk characters to your file). I then searched for the file extension (.3mf). The first hit was the "...BORDER.3mf". I wanted the border black, so that means I should start with black filament in the extruder. I searched for the extension (.3mf) again, and the next hit was the "....WHITE.3mf". I added the gcode "M600" to the line above like so:

M600
;MESH:Chess Board for MRB pieces at 50pct v3 WHITE.3mf

I then kept searching for the file extension (.3mf). and added the M600 before each of the ones where I wanted different colors for the first four layers. A total of 8 (eight) M600 commands should be added for two color printing. If you want the border a separate color you'll need M600 before each ;MESH line change inside the gcode for the first four layers.

If you want the contrasted look you need to change which parts you set white/black colors to.

This is a simplification on how I modified my gcode; my files were in the order "border, white, black". Yours may be different, so pay attention. The M117 is optional, it just adds some text to the display on your printer.

How I Designed This

The files were created in Fusion 360. There are some very thin lines between the squares of each color. This is to force them to be one continuous model, which gives three models in total. You can scale it and use it with any chess pieces you want, but they were originally created to be used with Mr Baddeleys chess pieces printed at 50% (as in the pictures).
