I’m mostly talking about Micro USB cables; they were pretty notorious for gradually becoming loose.
They definitely wouldn’t be a great fix and could potentially make things worse but for electronics you don’t plan on unplugging again or mind dying shortly after I could see them coming in handy if you don’t want to solder on a new connector or rely on strategically placing a device where the cable makes proper contact. I could see them being a weird item you stumble across on Ali Express.
Sure, the thing is, to extend the analogy, you are asking for there to be slightly smaller nuts. Nuts that for reasons imperceptible to the eye, won’t fit good bolts. Nuts for which a manufacturer would have to build new machines to make.
It given that you expect to import it via Ali express, it is no more ‘a just now’ solution than doing the job right.
Once I’m at that point I wouldn’t really be looking for that kind of precision. Just something roughly in that range.
Every so often I stumble across cables that are a tad thicker than others (usually they came with cheap electronics) so I know they are floating around out there. They’re just not labelled as being this way.
