This combination of nested Platonic and Archimedean solids is based upon an original video called UNIVERSO 1.0 by Mandala Matrix. Please take a look at 1:55 of the video.
These shapes (plus the vortex) are the basic building blocks of the material universe.
The shapes in this model include all 5
Platonic Solids PLUS the
Vector Equilibrium/Cuboctahedron and the
Rhombicuboctahedron.
