Some of the parts are remixed from the Modular Mounting System https://www.thingiverse.com/thing:2194278
This is for mounting a webcam to the side of your monitor with double-sided tape. It can be adjusted up and down by loosening 1 thumbscrew.
SideMount.stl and CameraBase.stl need supports and the rest don't.
All the parts are oriented the way I printed them.
You can print the M5x20 bolt but I recommend getting a metal one. The printed one breaks too easy.
The author marked this model as their own original creation.
