Terraforming Mars Hextile Holder (and Lid)

thingiverse

I'm using this organizer inside the Mars box, where it fits perfectly with its 50mm high design - approximately 70mm wide, depending on how you measure it. This is as tall as I can make something to hold both game boards at the top. That's because if I have the base game board and the Hellas & Elysium board in the box, I can place this organizer on top and it will meet the top of the game box's lip without any issues. The lid doesn't snap on but relies on the game box to keep things in place. Only time will tell if that's a reasonable assumption. A rubber band would be a great way to hold it together, applying frictional pressure along the side of the organizer while keeping its height the same. This design was created using Fusion360.
