Chess Board One Print to Rule them All

I was tired of looking for a simple solution for the chess board, so I made this. Printing this thing 4 times will give you a whole chess board that interlinks perfectly. No small parts and endless adjustments. One thing printed 4 times, and you're done.

Caveat - I'm yet to test this, so minor adjusments may be necessary for a good fit. Print a couple small ones to test first, just to be sure.

Will update as soon as I get it tested.
