This is a tilting mount for the foxeer XA T650M CCD 600TVL camera.
The angle is held by inserting screws into the back of the brackets.
There are 2 versions, the ones had the main bracket as a single piece, the other has it as two halves that are not connected. I found the separate version to be easier to get the camera loop part into.
The OpenSCAD files will be available on my dev blog, on the post that I wrote about this particular project.
Pillar height: 34.8 mm
Locking screw: M3
Camera Barrel Diameter: 15.4 mm
