Fold in half sideways then unfold. Heres another cool thing a puzzle made of four interlinked triangles. 9 This animation shows the construction of a stellated rhombic dodecahedron by inverting the center-face pyramids of a rhombic dodecahedron.

Assemble square-based pyramids to create an interactive stellated rhombic dodecahedron. Fold in half downwards then unfold. It shares its vertex arrangement with the regular dodecahedron and it is a stellation of a smaller dodecahedron.

Like many convex polyhedra the rhombic dodecahedron can be stellated by extending the faces or edges until they meet to form a new polyhedron. It is different from every other origami stellated dodecahedron model I have seen because 4 colors not 3 are used to make the model. The first stellation often simply called the stellated rhombic dodecahedron is well known.

My kids and I are proud of our creation and had a lot of fun building it. The anti-stellated version in red. This modular is made from 12 pieces of rectangular card stock in the ratio of 14.
