The clamp is suitable for use by small cameras like Hero or Yi 4k + and other similar ones. You can also use smartphones for shooting.
The clamp can be mounted on the shelf or edge of the table. Using the ball head - the viewing angle is not limited. Also suitable for other devices for installing cameras.
I used tubes with a diameter of 8 mm, a wall thickness of 1 mm. Anodized aluminum. Threaded stud - M5 length 110 mm. Rubber substrate can be printed with soft filaments.
Some parts have to be glued together, but I'm sure you can do it :) In principle, it was possible to make clamps and thinner, but I was reinsured and made a margin of safety. In the video, I showed the stages of assembly of some parts.
