Due to sudden interest I've just made these available on my Etsy store I'm also able to supply customised version of any size, colour, numbering. Just email me, email@example.com
The digital version of Tigris and Euphrates keeps track of how much power each token has connected to it. I wanted to make similar counters for the physical version of the game, they needed to be the same size as the existing tokens but able to display the numbers 0-19.I've made gaming counters previously and I didn't really like the deep recess down to the numbers so I went back to the drawing board when designing these.
The top layer has to be as thin as possible so it's made from 0.8mm birch. The magnet has to be stuck into a layer underneath and the numbers have to be drawn on a ring attached to a third layer to bring it back up to the same height. The tokens were painted in the appropriate colour and then engraved lightly which left the wood slightly stained in the right colours. (svg here)
