through the frame top. Figure 7.31 is a top view of the bottom chassis plate showing the four
attachment screw tops. You can readily see the four nylon spacers that support the tiltable

My only caution is to ensure that the movable platform that holds the camera is not
blocked in its range of motion by any of the mounting screws. I had to slightly notch the
platform to allow some clearance for the screws so that the platform could rotate throughout
a full 90° range of motion.
This tiltable camera platform project came out very well, and it is much less expensive
than any commercial product that will provide a similar function. The total cost of the parts,
without the camera, is less than $15.
