[Travis, how would you like a way to secure the box to the camera so you don't have to worry as much?
If you can find the screw, I can make you a strip of acrylic that you can screw to the base of the camera, and then attach the strip to the top of the box with a nylon thumbscrew. I don't have the threaded tap yet, but I'm going to get one soon. I think that would make it easier to hold on to.]
