Truncated Sphere D9.

This is my own interpretation of the D9. Please check also clsn's version.

This die is inspired by the repulsion force polyhedra. In fact, the underlying polyhedron (not rounded) looks like the shape that can be obtained through this technique with 9 points repulsing each others.
But in this case, I calculated the positions of those points to have a maximal radius for the circles resulting from the intersection of this underlying polyhedron with a sphere. The result is a truncated sphere with 9 circular faces of same radius.
It is numbered from 1 to 9: 6 numbers are on vertices, 3 on edges, none on the faces. The sum of the numbers on the upper vertices is 15. Same thing for the sum of the 3 numbers on the lower vertices and the sum of the 3 numbers on the edges. This numbering is closely linked to the well known 3x3 magic square.

This die is made of a shell of 1.5mm that contains support material to make it heavier. The engraved numbers have a 0.75 mm depth. This new version has big numbers that should be easy to read.
