Helmet mount for Contour video cameras

I didn't think the mounts that came with my Contour Roam were trustworthy so I quickly designed this one. It's got a bit of a curve on the mounting surface to match the side of a helmet.
Includes a detent bump with an integral springy rail behind it so the camera snaps into place.
This should be in pretty good shape as is but I have not ridden with it yet.
