3-Sided Coin inspired by Roman Numbers

Human: 3-Sided Coin - head and tails inspired by Roman Numerals. Printing with up to 100% infill makes it solid - my prints never quite hit the exact 3/3 ratio, but it's fun to have one. Maybe someday I'll need an uneven decision maker. I created this years ago. Perhaps I'm waiting for the outcome of something else before redesigning it and making the chances equal: http://think-maths.co.uk/downloads/three-sided-coin-activity
