Instructions revision: 1
I would not sell these instructions since the unit has four small cuts, which I have not been sure how to eliminate. I have diagrammed the unit as it is also because the result is elegant. The cuts are not even apparent on final product.
This unit is basically a version Francis Ow's 120º Unit with a color-change pattern, consisting of a hexagon with a pair of edges each bearing a tab and another pair serving as pockets. Therefore, it can produce any of the assemblies that are pictured in his instructions.
I thank Jim Cowling for instructions testing.
