A clamp that I use to mount a temporary light on a round tube. The clamp can accomodate tubes of 5 mm up to 40 mm. It is a linear clamp so the speed of the screw can be a little slow sometimes but it is sturdy.
It can grasp round, square or flat surfaces. If some rubber padding is added on the inside of the jaws more friction will occcur.
The clamp has 2 parts that fit right away due to the tolerance. You will need a M6x60 mm screw and a M6 nut.
The thumbnut of the screw can be downloaded from here: https://www.printables.com/model/506729-m6-screw-or-nut-thumbnut
I also added the Gopro adapter that can rotate 360 degrees.
