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.
