GoPro 3 cover for the Team Blacksheep GoPro Mount

I use the Team Blacksheep GoPro Mount on my Ritewing ZII. Unfortunately there is no cover available that fits the GoPro Hero 3. Well, there WAS no cover available :-)
Download, print, stick some foam on the back of the cover and screw the protective glass from the underwater housing on the front. Done. Now go fly and don't worry about your GPH3 anymore.
