Ventilation covers

[Saml8]

We are doing a custom build enclosure and because we live in such a dry area I want the ability to open and close the vents depending on how high the humidity is. Does anyone know where I can find these? Ideally they would be the small 2-3" round ones that can be adjusted on how "open" they are.
