These are grids for the game "terraforming mars" and they help to keep your resources and production markers in place. They print really fast (around 12 minutes for the small ones, 25 minutes for the big ones).
I also created a modified version of the production sheet, which better aligns the numbers with the grids. Instructions and new production sheet are in the attachment.
sliced with cura, wall thickness 0.4, printed as solid.
Added a cleaner and crisper production sheet image, called "TM generation final", both in png and tif format. These were made by MandyM11002. Thx for your contribution!
