What's your licensing for such photos? Can I include it in a blog post I'm writing on USB charging? With link back to this tweet, of course.

Is D+ suposed to be slightly smaller than D-, or that’s just the picture?
Manufacturing tolerances likely. USB Cable Spec, 4.10.1.1.2 Cable Assemblies: "Cables must contain two data-lines of 28 AWG, and a power pair of 28 AWG to 20 AWG. Power pairs smaller than 28 AWG are prohibited." https://www.usb.org/sites/default/files/CabConn20.pdf …
Fun project - snip the data wires to make a cable that will only charge and blocks programs getting into your computer/phone (and will not try to get contacts from your phone).
It'll slow charge though, to get anything better than maybe 5V1A you'd need a fancy integrated circuit
From just a casual observer and fan of your content, these cross section images are amazing...keep them coming!
Not typical of cheap Chinese cables. You don't get that much copper or a shield.
Strange arrangement. I will arranged the data + and - at each side of the power lines.
