I made this to fit the Foxeer Monster camera and the generic MG90S servo to add pan functionality to the camera. It will fit other 28mm cameras and servos with metal output shaft. The servo shaft hole is 4.5mm to make a nice press-fit to the servo.
If you need a mount for a 19mm sized camera see my listing here:

If you need a base to mount your servo to your plane, or whatever, here is the listing for the one shown in the pictures:
