3-Sided Coin - head and tails inspired by Roman Numbers.
Best to print with up to 100% infill to make it solid - although my prints never archived the exact 3/3 ratio, it is fun to have one. Someday there may be the need for an unequal decision maker.
I made it some years ago. Perhaps I wait for the outcome of this to redesign it and have the chances equally:
