The Edge Unit A is the first of the modular origami designs from Tomoko Fuse's 'Unit Origami Wonderland'. The edges form a 90 degree angle on either side.

I have folded the cube, made from 12 such modules. The model is quite firm and assembly was not too much of a challenge either. Overall, a pleasing modular to work on.
