3.5mm Patch Cable Cap (TPU 95A HF)

I have had issues in the past with my modular synthesizer patch cables incurring oxidation...which leads to unreliable connections between modules as well as regular cleanings with DeoxIT. I decided to create an end cap for my 3.5mm cables so that they are no longer exposed to the air, thus eliminating (or at least slowing down) oxidation. I went through multiple iterations of this model and originally printed it using PLA. This was a mistake because I've found that not all 3.5mm plugs are created equal. They actually seem to vary in size, ever so slightly. I think this is dependent on the manufacturer. I found that I had to make slightly dimension differences in order to accommodate the various brands of patch cables I own. This was a pain, for many reasons. Fast forward several months and I now own some TPU 95A HF. It occurred to me one night that I should simply print the cable caps using TPU so that they are flexible enough to fit any 3.5mm plugs. This turned out to work superb
