It's no fun fishing the right Terraforming Mars tile out of a ziplock back, so this storage tray and organizer lets you focus on the game instead. The eight slots each fit 10 tiles, so 6 for the city/greenery tiles (I like to orient three of them greenery-up and three of them city-up, but that's just cosmetic), 1 for the ten special tiles, and the last one for the 9 ocean tiles and 1 capital tile.
This was one of the first things I tried to model, initially in TinkerCAD, but I've now ported it to OpenSCAD just for fun. The model is (mostly) parameterized so you can play around with the variables in the file if you want to change e.g. the thickness or height.
It's a pretty simple model to print, I opted for .2mm layers and default PrusaSlicer settings.
The author marked this model as their own original creation.
