This structure has the general shape of a dodecahedron, with 12 beautiful pentagonal stars embeded in it. I found a while back a scan of the book Tomoko Fuse Unit Origami Fantasy. The book is all written in japanese, but I could make sense of the diagrams.
Tomoko Fuse is a master of modular origami, just google her name and you’ll find tons of fun projects.
I used craft paper to give the structure a muted tones and a rustic feel. I think it turned out pretty good 😊.
