This is an SJ4000 compatible camera holder and gimbal mounting plate for use with http://www.thingiverse.com/thing:185660
The camera holder has cutouts on both sides for accessing buttons, ports and the memory card and on the top for the main shutter button. A simple rubber band holds the camera in place. A large full servo arm holds the mount to the roll servo.
The gimbal mounting plate is designed to fit the common screw configuration of most regular gimbals. Two rubber grommets are used to provide vibration dampening between the mounting plate and gimbal.
The mounting plate should be printed with a high infill since that connects the entire gimbal to the aircraft.
