Light Proof Vent

cults3d

This vent will allow the free flow of air without any light transmission. It is good for photographic darkrooms or indoor gardens. An air vent in two parts. The outer cover can be whatever color suits your use. The light baffle is best printed dark or black. They are designed to fit a 35mm thick household door, and require a 3" hole. This is convenient if you have that 3" hole saw that you bought for 4 holes for a hydroponic build. Tolerence is tight, O.D. of the cover tube is 76mm, and I.D. of the cover and O.D. of the baffle tube are 72mm. I was able to snap everything into place with a little sanding of the baffle tube. Adjust to taste. Photos are of an outer cover without the baffle installed, and another with. One shows the baffle on the inside of the door, and the other is of the baffle finishing printing.
