I love the design of these pieces (https://www.thingiverse.com/thing:267298), however, I thought the bridge piece needed bkubicek's style applied to it.

You can print it with or without supports. Its right on the edge. I would just to make it cleaner looking.

bkubicek's pieces are 20mm scale. I reduced it down to 16mm a square so that I can print off the board (coming soon)
