I want to use Octoprint and have a view to my printer running and decided to create this little camera mount.
At the Anycubic Mega X the filament holder is a good place to fix it without much effort. You need a little bit longer screws as the one which are installed there.
The hole diameter is attached to the needed screw diameter of the camera. Having a inch thread at the camera (as it is always at cameras) I downloaded and printed this one too.
On the backside you can fix the wire.
