I want to build a cardboard venting contraption for my intake toblock the light. The shaded in area represents the wooden strips shown in the first picture. Once the strips are nailed to the wall, a piece of cardboard will be attached to the wooden strips to create the over and the 3 slits are the slits in the cardboard. I know theres supposed to be two 90 degree angles to block light leakage, but does this qualify?
thanks in advance!
