D10 with a 4-fold symmetry.

I did this one before knowing about the repulsion force polyhedra, although the shape is the one of the typical result you can obtain through this technique with 10 points : the dual polyhedron has 2 squares and 8 irregular pentagons. I calculated the positions of those points to have a maximal radius for the circles resulting from the intersection of this dual polyhedron with a sphere. The result is a truncated sphere with 10 circular faces of same radius.
It is numbered from 0 to 9. Only 2 faces are opposite one to the other and can hold numbers. The others have edges as opposite, thus the numbers on 8 edges.

This die has an approximate diameter of 24mm and is made of a shell of 1.5mm that contains support material to make it heavier. The engraved numbers have a 0.7 mm depth.

More informations in this post.

The current version has deeper numbers compared to the ones in the pictures (0.7 instead of 0.5 mm).
