Air intake duct with light lock and nut. (68mm hole)

Someone needed an air intake that blocks the light from passing through so I designed one. The hole you need to make is 68mm in diameter. I'm far to stupid to make this parametric, so this size wille have to do. You can always install 2 if you are unsure if the amount of airflow is sufficiënt. Just make sure to print it face down so it can print without support.

Just give me a shout if this was useful, always nice to hear.
