I designed this vent to use in my ~5mm thick acrylic diode laser enclosure.
The body is keyed so that it does not rotate when adjusting the vent opening.
While I am using this vent for my enclosure, I can not guarantee %100 that light will not make it through.

An SVG for the panel cut out is included.
The valve use an M3 threaded insert and screw/washer on the adjustable louver.
