    You may have heard me complain about making small cables like 3.5mm. I've never liked the bent metal strain relief. Then I came across glue hot shrink tubing, which I had forgotten about. I feel like I have more reliable cables using two bits of adhesive-lined heat shrink. I put one bit over the wires and one bit over the shroud and cable. The glue bonds to everything around it. With the two bits, I think I have a significant improvement in the soundness of the mechanical strain relief on these small cables. You can see a bit of glue peeking out the end of the heat shrink tube.

    Marine grade shrink tube is what most places will call it, or waterproof shrink tube. Might open up some buying options.
