This model can be found in Shuzo Fujimoto’s books, but only as pictures of the finished model in back-light:
- Twist Origami I, page 33 (labeled “C7”)
- Introduction to Creative Playing with Origami, front cover and pages 162, 164, and 167
Fortunately, this model can easily be derived from 220.127.116.11 Tessellation for which better instructions are available. Once that model is folded, all you need to do is purse the hex twists (form stars by aligning all edges of a hexagon with their closest diagonals).
