I am proceeding to fix on my own the first generation Macbook Air with a broken hinge. All the cables and connections are okay but the hinge is physically splitting open, with one side no longer connecting to the top display to the bottom. I have seen videos of how to open it, and it isn't hard, but my issue is how to find replacement for the hinge.
Worst scenario, I will be 3D printing the hinge. I have a makerbot, and don't mind DIY.
Please help! If I find out more, I will add updates here too.
