Origami Modular

This beautiful modular is from the book Origami New Discovery II, by Kunihiko Kasahara, ISBN 9784817080868.

I'm not sure about the name of model, as the book is in Japanese. I liked it because each side looks like a rose. It consists of 12 units that are very easy to fold and assemble.
I folded each unit with a 3" (75mm) square of duo origami paper, solid color on one side and patterned on the other.
