This is an adjustable-tilt light-duty mount for a Go Pro Hero2. The open top/side design makes it easy to insert and remove the camera. A clip is used to hold the open side together and provide a bit of retention force (a small beveled protusion on the inside back of the mount presses against the cam and holds it in due to friction via the clip squeezing the case together slightly). The lens surround extends about 1mm in front of the lens forwardmost surface for front impact protection - unfortunately this makes the surround visible at the lower edges of the video at the wide FOV setting (I mainly use the narrow setting for my videos which is not an issue). Tilt retention is via bolt/captured nut.Print the 4 pieces out. Bond the support piece to the bottom of the case (I print primarily with ABS - I found that by smearing acetone on both surfaces and clamping them together for a few minutes results in a very strong bond). Make sure you are bonding the support piece (with the single "ear") to the case, don't bond the base piece (with the 2 "ears"). Use an M3x12 bolt and nut to secure the case/support onto the base and tighten to hold at your desired angle. Now just insert your Go Pro 2 and slide the clip down over the sides to secure it.
