polypropylene sphere1 Sphere_laser cutting Laser cutting time – 14 minutes. Size of the sheet – 68×36 cm Size of the spheres – 12 cm in diameter laser cut_assembly1   Sphere_strategy 1 Polypropylene sphere1 We divided sphere into 10 equal slices by cutting the sphere with radial planes, after that  we applied twisting to these slices by 60 degrees. By unrolling surface of the slice we were able to have 2D element on which we made joints suitable for flexible material such as polypropylene.   Sphere_strategy 2 Polypropylene sphere 1 The second sphere was created by dividing sphere into 12 equal slices, also done by cutting the sphere with radial planes. Here, we experimented with folding detail on two points of sphere where slice sheets meet.
