Air Vent Grill with Backdraft Shutter Ducting

Wall mount adjustable Air Vent Grill with Backdraft Shutter Ducting (170/250/45) Insert part #2 into part #3, then slightly bend part #1 into the grooves of part #3. Carefully bend parts #5 and insert them into the holes of part #4. To print the plate № 4, use a PETG bonding layer or Support for PLA/PETG in the support. Use a 3.5mm drill bit to align the holes. To make the stationary parts more stable, use a little super glue. To attach the ventilation grille to the wall, I used double-sided tape.
