Heads/Tails Cube

thingiverse

This is a fifty-fifty probability die, where either side of the cube will land facing up when it's rolled. The outcome is entirely random and unpredictable, yet perfectly balanced between two equally likely possibilities. Whether you call it a coin toss or a dice roll, the result is always one of these two options: heads or tails, 1 or 6, success or failure – each with an equal chance of occurring.
