I found a Phoenix 3.0 I made from the crease pattern on Satoshi Kamiya’s website, and it looks pretty good. I thought a Ryujin would go well with it. The only one I hadn’t made was the 3.1, so I thought I’d try that.
The 2.1 crease pattern is on his website, and the 3.5 is in the Super Complex book. I found the 3.1’s crease pattern on the internet. It seems to be off of a card from one of his exhibitions (he has cards under the model with the title and it sometimes has the crease pattern on it). So I’m not 100% sure about it, but it’s a lot like the 3.5 and was fun either way.
I think they look neat together.
