Terraforming Mars Player Card Holder

This is a two-part case holder for a Terraforming Mars player card. It completely incases the card, ensuring that it cannot move around. The cube holes are 8.5 mm square which ensures that the pieces fit well and do not move around. The numbers are sunken so that they do not interfere with the cubes.

I've printed this on a Prusa MK3S+ in PLA using the “0.15mm QUALITY” profile. I recommend printing the top part in two colors to ensure that the numbers are clearly visible. You can see an example using blue and transparent filament (which is not really transparent).
