Camera mounting in acrylic

Making a mount out of acrylic and the camera is between two layers of acrylic. Do I need to drill some holes for venting? Any issue with heat from the camera board?

I’ve seen a few designs that are open on the top and bottom. Personally I don’t like this as I place more importance on keeping debris off the circuit board than the need for cooling.
Mine is enclosed except for a small slot to pass the wire through.
Think cell phones. They get plenty hot, are enclosed and shoved into a case. No problems.

I modified a design found here in the YALCM thread. Happy to share the design if I knew how.
