Today I installed the air vents.
I started off by creating a circle template for the holes I needed to cut into the Lexan. I used the rotary bit on my Dremel tool to cut the holes. I cut a practice hole in my spare door Lexan to make sure the bit wouldn't damage the Lexan.
I taped my hole templates to Lexan where the instruction manual stated. Once the holes were cut out I was able to pop the vents into place. The vents fit very snuggly into the holes and will only rotate if a significant amount of force is used. I may try to enlarge the holes at a later date but I don't want the vents to rotate too easily.
