Number of units: 12 (6 for cube, 6 for alpha)

Designer: Tomoko Fuse

Instructions: The model is composed of a basic Sonobe Cube along with 'Alpha Units', which are described on Page 74 in the book Multidimensional Transformations: Unit Origami by Tomoko Fuse.

For the cube, you may see instructions for Sonobe units by Dave Mitchell: Part I and Part II. To assemble the units, Instructions for Assembly with Sonobe units (PDF) — this is a free chapter from Meenakshi Mukerji's book: Marvelous Modular Origami (2007, 92 pages).

Comments: The alpha units do not fit snugly into the cube. So the final model is not as neat as most other modular origami models.
