Prism-Expanded Dissected Cuboctahedron

Stewart investigated various criteria for finding interesting toroids. Of the models which satisfied all his criteria, almost all of them had a convex hull with all regular faces. He eventually found a counter-example, but it had some excavations which did not increase the genus of the model, so it did not strictly satisfy all of his criteria.

It seems Stewart was unaware of this model however, which Alex Doskey discovered more recently. It satisfies all of his criteria perfectly, but its convex hull has some rhombic faces. It has a genus of 11. See also my genus-41 toroid.

Start by putting together the inner section. Then glue the outer parts around it.
