Okay... I actually don't have the diagram for you, guys. It was found in a book. The title is "ORIGAMI OMNIBUS" by Kunihiko Kasahara. It's a great book, because you can found more complex origami mix with easier ones. It also explain briefly how to create and fold base from the developmental drawings. Easy origami books are easy to found. It's more complicate to get complex origami books. You almost need to command online.
I love how it looks 3D.
