Terraforming Mars Grid Marker Holder

These prints are to help keep the Terraforming Mars board game resources and production markers in place. I really wanted a simple print that allows me to see the card underneath with additions for 10x and 20x indicators and most importantly - something that would print on my small printer. I've included the whole piece as one, as well as a left and right which can easily be glued together. The photos I've included are 2 pieces glued together with Testors model glue.
