Fun Fair Dice! n-gon, tallies, circles.

Files include STL and 3MF files. Also included a Fusion 360 file of a blank die in case anyone wanted to play with that, but I think most people can just model their own cubes :). Dice #1 - Tally marks. Had each depression compensate for the amount of area each respective tally's area. Dice # 2- n-sided polygon. The number of sides tells you what side your on (e.g. triangle 3, hexagon 6). What is a 1-gon? I decided its a circle. What is a 2-gon? I just put two rectangles and called it a day :). All depressed 0.2 mm to minimize amount of material taken off. Dice # 3 - found on the Thingiverse link. Made an excel sheet that calculated the radius of each side's circles so that all the circles add up to the same area (area of six 6-circles equals area of two 2-circles). Of course, the distribution of mass won't be uniform, but they're only debossed 0.2 mm so hopefully it doesn't matter much. Recommend having top layers and bottom layers be equal to number of perimeter walls (or 100% infill).
