These were some of the original 3D models that I created in the process of developing the Piston Ring. I printed all three of these designs, but each of the first two had their own unique problems. The first design was certainly the most complex and interesting, but I found that making a mixing ball into a piece of wearable jewelry had a slew of problems. In addition, printing designs like it at smaller sizes would ruin the fidelity of the model. Moving on from that idea, I began iterating designs for rings that store workout powder. The second design had three major issues: the container was to big to look good when put on a finger, the ring portion itself was too thin to resist the torsion of people pulling on it when trying to unscrew the cap (and it even broke!), and the lid was too thin for people to grasp with their fingers. Plus, with the threading on the inside, powder could easily get stuck and ruing the tolerance. My final design fixed all of these issues, but required more tolerance than its larger counterpart.
