Martin Gardner Modular Origami G4G12 Rhombic Dodecahedron

At the 12th gathering for (Martin) Gardner my gift exchange was a modular origami project consisting of 12 A4 sized pages with instructions. When correctly folded and assembled, the result should be something like this.

The 12 pages must be printed on A4 size paper (or A5, etc., or anything that has a length to width ratio of √2). The artwork was made by Scott Kim and stretched and clipped to correctly fit the faces of the Rhombic Dodecahedron. Graphics re-used with permission.
Here are the assembly instructions.
