The external shape of the polyhedron is identical to the “Great Icosahedron”.

The main difference is the absence of internal edges of the core.
The design is almost weightless, which requires effort during assembly.

Assembly

To assemble this polyhedron, you can use the details of the set "Magic Edges #9".
We will need 12 blanks in the form of "pyramids".

1. We stick together 5 pieces—blanks in the form of a five-pointed star.
To do this, we will need to lay all five blanks on a flat table surface and not “bother” them until they are scorched.
Apply the glue with the tip of a toothpick. At first, only at the "middle" level.
Judging by the photos, it may give the impression that the glue is abundant.
However, after drying, the glue recommended by us (Super-PVA) will significantly decrease in size.

2. Let the glue dry for about 1 hour.

Then glue through the bottom level.

3. Repeat the operation for five more workpieces and get two sets for the assembly.

4. After pasting two blanks, we add a new “beam” on top.

5. Since it is necessary to create a flat, stable surface for gluing the last ray, we recommend using an ordinary cup or cup. We turn over the polyhedron and set the last ray to the free space.

As a result, we obtain a very interesting polyhedron with a hollow surface inside.

In fact, the “5th stellate icosahedron” polyhedron differs from the “Great icosahedron” only by the absence of internal faces.
