Edit:
Any suggestions or help is welcome (I’m quite new to this forum and this kinda stuff in gerneral)
Edit 2:
Maybe this could even be used to charge the Laptop itself as it only is a Cable. Handy for when you forget the charger but have a usb c outlet.
Before buying anything or 3d printing, I’d suggest checking that your phone & your service provider will cooperate. By trying it with whatever cable you have now.
Some cell phone plans do not allow tethering. (click to show)
They’ll attempt to block you. Telling your phone to not offer it to you as an option, and I believe many phones will obey. You didn’t think you controlled the device you paid for, and supposed to “own”, did you? If you have root, you do own your phone of course (mostly). But service providers monitor your traffic for fingerprints of tethering, so you’ll need an app that hides that. There should be a few. One I know of: github.com/Mygod/VPNHotspot
