I used the Logitech mount as a start by notnyt. I wanted a bed mounted camera mount for the Raptor 2 printer. It's designed with a slot on top to use with a standard tripod style 1/4-20 screw mounted camera.
The mount holds the camera back from the bed far enough so as not to contact the carriage.
I used a 1/4-20 bolt to attach the mount to the bed at the T position of the Raptor cutout. It's a snug fit but I guess that's good.
Printed this on on its side with supports for the slots.
