Mobius camera webcam support

I designed this webcam support to be able to use my Möbius camera as a webcam, either facing to me of pointing to the table so that I can show some electronics I am working on or simply a sketch I am drawing on a piece of paper.

About 400g counterweight is needed on the base plate so that it does not fall in any position of the camera.

This design is a remix of C270 Support for Ender 3" by Waverunner62.
Only the arms are used without any modifications.
I imported the stls in Onshape and redesigned the needed pieces there :
