Multi-Level Box v1 (4 Units)

DesignedAug 2017
Crease PatternYes

This model uses a 36 x 18 starting grid. The box is flat foldable, and the box units in this model can be used as a tessellation. Only 4 box units were used in this model, but theoretically an infinite number of boxes can be tiled vertically and horizontally. My first idea while designing this model wasn't very efficient - this version is 30% more efficient than my initial idea.
