Instructions

Choose a size and make 1 Initial Face, 1 Second Face, 4 First Level Faces, 4 Second Level Faces and 1 Closing Edge in the same size.

Check the diagram, read every step before joining any pieces, and be sure to understand how it works. You can use pieces from other steps to help yourself check the geometry and join with the right angles. In this polyhedron it is very important, not only diedric angle (117º), but also to check that every face is a regular pentagon, and that all edges of each face are in the same plane.

Attach Second Face to Initial Face, 117º angle, with a small bead. You can use a First Level Face (step 4) to check the angle, or attach them at the same time.

Attach one First Level Face to the structure, as the diagram shows, with a small bead. Attach 2 First Level Faces more.

Complete half dodecahedron by attaching one Second Level Face, as the diagram shows, with a small bead.

Start the second half by attaching the last First Level Face, as the diagram shows, with a small bead. You can use a Second Level Face (step 7) to check the angle, or attach them at the same time.

Attach 3 Second Level Faces, as the diagram shows, with a small bead.

Finish the structure by attaching the Closing Edge, as the diagram shows, with a small bead.
