OPX2 is made of 8000 aluminum rods 15cm in length and 1.5mm in diameter. 3D printing technology was used to fabricate each of the 2000 connections making it possible to aggregate the structure by holding each rod at an exact angle. The modularity of parts allows for Opx2 to expand and contract to any size. The photos represent a structure that is 2m x 2m x 2m and assembled with a violet gradient of connection parts.
