Speaking of office supplies, a box of mailing tubes showed up in our Museum of Mathematics office and I couldn’t resist making a geometric construction. All you need to make your own copy are thirty tubes and sixty rubber bands. All the tubes are surrounded similarly. Each touches four others, approximately outlining an icosidodecahedron.

I showed this to Keith Hoffman and he made the same structure from 510 Lego studs and 60 tiny clear rubber bands.

What can you use to make this structure?
