Ventilator grille - 150mm

I needed a grille for a 150 mm ventilator which fits only partially into a wall, and partially stands out.This is made in particular for Dalap 150 SD, but should probably fit any circular 150 mm ventilator. This will fit if your ventilator stands out for at most 20 mm from the wall (measured on the ventilator wall, not the center). The total ventilator depth this grille can cover is 50 mm. I used 3.5x45 screws to attach it to the wall.
