JBL Tune 720BT + Tune 770NC Hinge Piece

These JBL hinge pieces have a habit of breaking in my experience, so I cadded up some new ones. They are not perfect, but they should work and STEP files are attatched if anyone wants to make improvents! Should fit 770NC and 720BT models. Warning: some pretty tiny soldering is required, and it can be difficult to fish the cables through the small openings.
