Summary

Kamas are the monetary unit in the world of the French game and anime, "Wakfu".

These counterfeit kamas wouldn't fool Ruel Stroud, but I bet that crafty old Enotroph would be interested.

"You have a machine that makes kamas, you say?"

Good for cosplay, especially if painted or printed in gold colored filament.

Instructions

I printed in PLA with a layer height of 0.2mm and the shell and top/bottom at 0.8mm. If you make the top/bottom too thin you will
get gaps.
Printing in one piece looks OK, but on some prints the bottom came out a little stringing where it is not supported. I tried to make the model as good as possible for printing in one piece.
Printing with support did not help; in fact it looked worse.
Alternately, you could use your printing software to print only the top half of the coin (Cut off bottom in the Advanced tab on Cura), print two of them, sand the bottoms flat and glue them together, but that's a lot of work and I'd rather live with a slightly stringy bottom half of the coin.
In the end, I bought some gold colored PLA filament, and it came out great.
