I really like the USB Microscope Holder of this modular stand https://www.thingiverse.com/thing:2780973 and this holder https://www.thingiverse.com/thing:2783956 both made by user @ChrLee. Congrats to him.

I needed a connector to my third hand that wouldn't shake and wobble to have a stable picture. So I designed the connector with a base plate and 2 screw heads.

So just choose the parts from those two models above and add 2x M4 screws and nuts and

Enjoy!

NOTE: Tried to remix both things from Chris, but somehow I was unable to manage it, so I had to add a new thing. :(
