Louvered Vent with bug screen

thingiverse

I designed a louvered vent to exchange fresh air inside my travel trailer, also incorporating a bug screen to prevent larger insects from entering. Both 2-inch and 3-inch versions have been uploaded, along with multiple models for various depths that can be combined and matched between .5 inches and 4 inches of wall depth. The louvers are angled at 30 degrees, eliminating the need for any supports.
