Third Stellation of the Icosahedron
This model is similar to the small stellated dodecahedron in that each pentagonal face contains a pentagonal pyramid. However, in this case, the pyramid is a dimple and not a stellation.
Notice that you can see 3 blue triangles that are facing slightly left and downward. Those 3 triangles are in the same plane. You can also see 3 dark green triangles facing slightly upward and to the left. Three yellow triangles are in the same plane and facing slightly to the right and upward.
You can use the same color arrangement that was used for the icosahedron. Assemble these dimples in a counterclockwise rotation as seen looking into the dimple.
