Nice work, paco. I recommend a somewhat tedious method to improve the performance of the DC run, by tightly twisting the conductors, then wrapping them with heavy-duty Oatey FASTape PTFE Teflon tape, which is easier to do than via the regular white colored PTFE Teflon tape that's very thin and takes forever to properly wrap a cable assembly. The Teflon tape wrap is an effective way to mitigate cable resonance issues of an unjacketed hand-twisted pair, IME. It also keeps the two conductors firmly coupled together, along the entire length of the cable without gaps and spaces between the conductors. I like to use it instead of heatshrink in most cases.The heavy-duty Oatey FASTape is also a very useful tool for various other cable building projects, including making a custom strain relief that resembles a molded type strain relief. I also use it to insulate the inside of various connectors such as a small DC plug to avoid the contacts touching each other. Many other cable building issues can also be addressed with the product. My favorite so far is not using the heavy barrel of a 6.3mm stereo headphone plug, and creating the equivalent of a molded plastic connector, but with a much better dielectric and vibration damping qualities. Medical tape is also a good tool, but that's another story.

thanks, but your suggestion sounds me like a drop in the bucket; if you try my 2 legs cable the real problem is soldering 5 wires to the USB-B plug, 2 of them solid, 20ga; among other things you need a lead hand! that's suffering!!... :)
I hear you, paco. It was a tough job to terminate both a 24 AWG VH Audio V-Twist cable and a 21 AWG aggregate gauge V-Quad cable with a set of USB connectors.
At least the Viborg USB connectors I chose feature a large connector entry point with a set-screw strain relief mechanism. That was the easy part of the DIY project.
yep, i got the Viborg plugs long ago, but they are still unused... those covers are too heavy for my taste, and the plugs themselves can be ordered independently
