[Origami] What model is this?

I made this model many years ago. Over time the connections have loosened and the "hole" has become larger. I'd like to make it again but forget the name of the model. Help? https://drive.google.com/file/d/0B7j_htDbzCW1bC1aU0VaLXF3STg/view?usp=sharing Thank you! Andrea
