2020 Modular Polyhedron

Design and develop a metallic polyhedron that contains multiple identical units and each unit or modular should consist of no more than three kinds of pieces. This polyhedron should be visually attractive, and its aesthetic value should be aligned with its structural value. All the identical units need to be assembled without using any type of glue or adhesive. All the cuts and folds need to be well designed and precise in order to fit the units together nicely. Due to the different thickness, paper, cardboard, sheet metal all have their unique properties. choose materials for your final deliverables, understand the properties of the material, the limitations and constraints of the fabrication process, and experiment with multiple prototypes to study the structures and assembling process.
