The octahedron has 6 vertices which line up with the “faces” of the outer spherical dice. By placing a small weight inside (I used a 7mm ball bearing), when this dice is rolled, the ball bearing will always fall into one of the inner vertices and the opposite outer face will face upwards. I did a small sample of rolls with this dice (n=50) and got a pretty even distribution of results. I may end up doing a larger experiment just to see how “fair” this dice actually is. There are two print profiles:Multi-Colour Dice - This profile is for AMS users and has coloured spots a split parts of the model, so any two colours can be used. This is the version I used for my fairness testing as it has the most even outer surface (prints at 0.12 high quality with brims to ensure good bed adhesio
