MOC-10184 Concentric “Spheres” (Truncated Octahedrons)

These Lego Technic “Truncated Octahedrons” ( https://en.wikipedia.org/wiki/Truncated_octahedron   ) are made from just a few completely different Lego Technic components.  They type a sphere form having 6 sq. sides and eight hexagonal sides.  For the innermost (yellow) Octahedron, the Lego Digital Designer (LDD) .lxf Building Instructions and Parts List could be discovered by way of https://www.flickr.com/photos/42988571@N08/36838496752/in/datetaken-public/ .  The lengths of the Technic Axles improve by 2 studs (2L) in every successive layer; in principle one may hold making bigger and bigger Octahedrons perpetually!
