Felt sphere For experimenting with the material we chose 5 mm thickness felt. The sphere is composed by 8 triangular pieces of 2 types and together they create a simple anchor joint . By testing the joint we were able to assay the tensile strength of the material which turned out to be good. Since the material is a soft textile, it does not keep the shape so the sphere looked squared depending on the angle of the viewer. Laser cut parameters: – Power: 130 – Speed: 60 – Height: 2
