Remix of GoPro Ground Spike

There were two (very trivial) reasons why I remixed this thing. First of all, I found that the holes and spacing in the original were a little bit tight although it didn't take much to get everything to fit as it should. Second reason was simply that I wanted to draw something on my computer which I could then print and use with my new GoPro Hero 3+. The design - including the length - is pretty much identical to the original which says a lot for the excellent work by Joe_Murphy.
