I made this in the laziest way, so the overall dimensions are correct but the centimeters marks aren't precise, some are slightly off.
For casual play when both players don't care about 1mm errors, it does the job.
Edit: Did a V2 with triangular marks that are correctly centered, so now it's precise. Theoretically. I will print later to see if works better than rectangular marks.
