Spiked Icosahedron (Paper Airplane Sonobe)

Spiked Icosahedron made from my new Sonobe variant, Paper Airplane Sonobe. When you look at an individual unit before assembling the model, you can spot a red arrow which looks like a paper airplane seen from the top. In the assembled model, the tips of these airplanes are covered by white parts from other units, but you can still see the pattern.

I used units much smaller than I usually fold (6 cm paper) but this allowed me to cut 32 squares from just two sheets of 25 cm Kami.
