This is NOT an original model but simply my attempt to bring this useful item into view for people who might be looking on other sites anymore.

This webcam mount is designed to mount the uShining Webcam onto an Ender 3 V2 by clipping onto the QR Code Cover.  
 

Printing

I printed this in Polymaker PLA at .2mm layer height.  No need for any supports.

Assembly
In order to make the camera fit properly you need to remove it from it's folding base.  This is accomplished by peeling up the cover tape to expose 4 screw holes and removing those screws.  You can then unscrew the ball & socket mount and remove the camera.  

To mount the camera to the clip you need to reverse the ball joint (face the rounded part down) and re-screw it to the camera itself through the camera mount.  Do NOT overtighten as the screw can and will break.  

The Mount then simply clips the QR Code Cover.

You'll then need to rotate the image 180 degrees in Klipper / Octoprint and you now have a nice camera set up.
