The concept behind this investigation was to design a joint that was capable of a number of different motions; rolling, rotation, and expanding. These motions are further articulated when these individual units are connected to create a linear system. Each unit has a rotation limit of 355 degrees, which creates an interesting spiral effect once the system is fully expanded. As the units begin to rotate out, they consequentially expand in length by only 3 millimeters before the unit reaches its maximum expansion limit. The joints are printed as a connected system and vary in terms of certain parameters. The differences in the arm widths allow for the connection between the joints have varying articulations. As the width of the openings get thicker, the joining of the two units becomes less visible, and at a certain point, becomes flush with the arm. As the width of the opening gets thinner, the connection between the two units becomes more visible and more flexible in terms of disassembly. The second parameter is the variation within the arm length, which creates a secondary visual motion through the implied undulating edges.
