Got busy trying to figure out a way to get my Contour cameras back into service. Decided to go the 3D Printed adapter route. Why spend the money on two adapters (Contour Tripod Adapter + GoPro Tripod Adapter) when you should be able to go directly from the T-Rail mount system the Contour uses directly into a GoPro mount. There are so many more GoPro mounts and they are so much cheaper than anything from Contour. This works on all current and discontinued Contour cameras that use the T-Rail mounts.
