A new and unusual way of making a model of Stellated polyhedron was discovered by a German mathematician and astronomer Johannes Kepler in 1619.
In one of our previous articles we told you about a challenging task to make a polyhedron having just six identical figures. In November, 1984, there was published an article in the magazine called "Quantum” which described how to make a stellate octahedron with the similar principles.
The author of the article, Igor Glushkov (from Obninsk, Russia) offers the following idea. The stellated octahedron (the other name: Kepler’s “stella octangula”) can be cut into 4 equal parts and get a challenging task out of it. The main aim is to assemble these parts to get a polyhedron. Each of the part can be made of a cardboard. To assemble a polyhedron you will need 4 printed sheets of that model.

The steps are as follows:
Pay. attention that red painted area should be inside the polyhedron, while the blue one is the outside
