This is a curved dice, made with Mathematica and modified with Tinkercad. It is an octahedron, and is created with the equation sin(x) + sin(y) + sin(z) = 0. This was made by both myself and a friend. The dice was made with Mathematica, and the numbers with Tinkercad. Not tested yet!
Print the file out and attach the bottoms of the pyramids together with glue. Leave to dry, and then play a game!
