Copper nuclear structure

This blender file of an atomic nucleus has a better quality than the previous nuclei of Fe, Ni, and C. This Cu nucleus has all spheres connected. This allows a 3D printer to print one solid model, not a loose set of balls that collapse. An stl file is also provided, so the Thingiviewer can be used to rotate the simulated copper nucleus.

White protons, blue neutrons. Six pyramids of nucleons on a cube of nucleons. A cube has 6 sides, so 6 pyramids cover the faces. The lattice is called Face Ar
