Macbook Air Magsafe locking clip

My battery stopped working in my Macbook, and if the charger came off it just shut off immediately! So I needed to make something, to keep it from coming loose. 

This hooks into the edge of the hinge, and if you use the Extreme version it also hooks under so it cant be knocked upward. so it stays even if its on your lap or if you put it down on the bed. 

I recommend some support, and a fine layer height.
