About this 3D model
I needed numbers to track enemies on the board and their corresponding gamecards. I found a blank coin model on Thingiverse (Ridged Blank Coin) that I used as a basis. I resized the coin to 20mm and added the ingraved numbers on both sides. Printing the coin thinner then 2mm gave it a real flimsy feeling when handling. It would break easily. I also needed a smaller version of the number to put next to the miniature on the table. I resized the coin to 15mm, keeping the width of 2mm. (see picture) I finished these by painting the coin metallic gold and the recessed number in matt black. It gave a nice contrast without disturbing the battlefield.
