15x7 Return air duct vent

This is a return air Vent i designed to replace some unappealing vents in my house. 15.25x7.25 size. Thicker at the base then narrower up top to give it a nice aesthetic look when installed. This print does require a 300mm build volume printer. Print faily slow with some z hop enabled otherwise it cause issues with the thin cross pieces and knock it over. Designed for no supports or brim needed. Rotate 45* with wide base down, part standing up.
