This shows 5 interlocking tetrahedra arranged with their vertices forming a dodecahedron. Read more on the Wikipedia article. For even more, read John Baez's notes in his article on the 600 cell (part 2).

Instructions

Several experts have called this model "challenging", and I agree. But it's not too difficult. I suggest looking through the following before you start.

• Thomas Hull's instructions
• Michal Kosmulski's further details
• Dirk Eisner's alternate instructions (a comment on a Flickr page)

When you're ready to join the triangles, pay very close attention to the over/under pattern in the instructions you choose to follow. I found that what I wanted most was the ability to rotate the examples slightly, and that's why I added the interactive spinner for my model. I hope it helps!

More papercraft!
