For experimenting with the material we used a 1.2 mm thickness sheet. Before starting the milling the brass sheet was attached to the machine’s board using double sided tape and 6 screws distributed on the edges. The RinoCam file was set using “2D Engraving” in 2 steps of 0.6 mm each; the first one contoured all the triangles of the origami pattern and the second one cut them leaving 0.6 mm bridges that allowed us to fold the piece. In spite of the total depth of the milling was 1.2 mm as the material, some areas were not cut though. The solution found for next experiments was to increase the total depth of the cut.

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

The piece was made in the Makerbot 3D printer. The joint consists in a hard center with 12 arms made to be attached to brass triangles. Each arm has a 1 mm of diameter hole to lock the arm into the brass by adding an additional stick piece. The precision of the 3D printer is not enough for the dimension of the hole and the arms were too long so they easily break.
