Fix a Macbook Air charger

I so love my Macbook air, so light, so easy to carry. I have it with me all day long, hence the plug ending started to break. A little piece came out. Sticky tape made it work for a while, then I feared I would lose the piece. sugru fixed it and here it is looking very okay. FYI, the LED lamp still shows red or green through the sugru if you look really close.
