7 intersecting planes - stars.
I love star planes than rectangular planes. So I stopped doing rectangular ones given in the book. (Anyway number of units started getting too many, it takes time to fold and assemble).
Reference : Ornamental Origami: Exploring 3D Geometric Designs
No of units: 7 x 6 = 42 . 7 planes 6 units each.
Paper used: Color printer papers
Paper size: 4 inch x 4 inch
Time : 4-5 hours (I didn't complete these models at one stretch. I took 2-3 days spending 2 hours per day)
Base angle = 360 / 6 = 60 degrees.
Assembly Technique: Start by connecting 6 units. In the photo the hexagon which I started is towards left formed by red, light purple, light blue, green, orange and yellow. Baby pink is the 7th plane.
