Two Unit Modular Excavated Octahedron

This model is an excavated octahedron, which is a polyhedron based on the octahedron, a Platonic solid, and a deltahedron. An excavated octahedron has 24 faces, unlike a normal octahedron, which only has eight. This model is made entirely from the base template with no other creases. It is also fairly easy and is a good introduction to modular and geometric origami.
