Mk2 ground spike/tripod for gopro

A neater, compact tripod that's much easier to stuff in a camera bag and more robust than http://www.thingiverse.com/thing:297994
Still also works as a dirt spike.
Legs can be printed in half and super-glued if the overhangs are a problem.

NEW:
TripodExtension allows the tripod to fold back behind the camera when not in use.
