Nested Dodecahedra, Russian Dolls

3D model description

Nested Dodecahedra
Nested structures are everywhere in mathematics--recursive functions. Here is a sequence of 15 dodecahedron shells, ranging from 48mm to 6mm in terms of exterior edge length. You could choose any number from them and make a nested structure. It takes two halves to make a whole, of course. Each shell is 2mm thick; its edge length drops by 3mm. By the way, how does the volume of each dodecahedron change, as the side length goes down by 3mm?
