House outside vent

This is a house vent to replace your old one. It fits perfectly with in the measure in the photos. I recommand printing it in PETG because it is a vent that you put outside and PETG is a solide material that resists sunlight. The small pins that you see on the 3D modle are made to clip inside the vent. To clip the vent you can use a flat screwdriver to skweez it in place. If the pins are not in the right place you can cut the ones that are bulky.
