I'm new to 3D printing and CAD, it's not the best looking, I was going for fast printing. I borrowed a couple of files from the internet to get the dimensions of the charger and the thunderbolt.
You might want to print it laying down, so the layer lines aren't at the breaking to get stuck inside your laptop , but nice altogether! My charger has long died, and I'm using a USB c to mag charger that mostly works (and still disconnects if you look at it funny)
