A while ago the hinge part of my Microsoft LifeCam Cinema webcam broke, it's a great webcam for wfh calls and didn't want to spend money to buy another one. So I designed a replacement hinge that it's easy to print.
Changing the hinge does require a bit of work since the camera is a bit hard to disassemble, I followed this guide - http://dslrmodifications.com/lifecam/lifecam1.html. I also had to use a longer M2 screw to get the two part of the hinge connected ( about 9mm in length )
I'm including the f3d public link for anyone that needs it.
