(0,0,12,45)-deltahedron with an axis of 5-fold symmetry, and a plane of symmetry perpendicular to it.

It is completely rigid, and highly reminiscent of Alain Lobel's frames.

It can also be seen as a snub dodecahedron where the pentagons are replaced by pentagonal pyramids, and where one band of triangles is missing.

This structure can be further extended in the same way as the families in Alain Lobel's frames, by increasing the distance between the pentagonal elements.
