I have a thread started here about 3D printed mounts: http://www.bikeforums.net/electronic...es-mounts.html, that thread also has a picture of the original printed mount on my bike with a Sony HDR-AZ1 mounted from the seatpost. You can use 3 mm socket head cap screws and lock nuts to mount it, as I did. The mount itself is an exact fit for GoPro and will accept a standard GoPro 5 mm thumbscrew and acorn nut.

It could be made with larger clamp sizes but I don't have a need as every bike I currently ride uses a 27.2 seat post, and its really a tedious job reconstructing someone else's 3D files when all they provide is an .stl (mesh) file for 3D printing. My Thingiverse listing includes the FreeCAD file too.
