"Le berlingot"(396 or 168 rods) or snub expanded deltahedron

Last january I made variations around a snub deltahedron starting from one of the bulbs of my giant hourglass.

The berlingot otherwise called Humbug in English is this:

A famous packaging brand also made it popular.

This one counts 396 rods (including 18 for the base) and 134 spheres

Detailed Howto here for the 396-Berlingot.


I had the secret hope it would be a first, but by looking a little, I saw in the geomag wiki that others thought about it before me ...
However, I did not see anyone produce a model as big as mine because I don't think they achieved it by my method based on a Truncated icosahedron. It's an interesting way to do it. See the detailed Howto here ;-)
It's a sort of crease tatrahedron (2nd column on the picture) or snub expanded deltahedron.

It is close but it is not that model seen several times (dihedron family):

It has one more dimension

The giant model cannot rest directly on one face, otherwise it will collapse under its own weight.
Needs a base to hold it on one of its vertices:

The mid-size model - 168 rods and 58 spheres (detailed howto):

Look at these beautiful intertwining color curves!
