Air Vent Cover

Since I needed to cover a pipe outdoors, I used ASA as the material. However, if the part is located indoors, you can easily print it in standard PLA. The object is designed to fit into 125 mm pipes; the section that slides inside the pipe (or wall) is 123 mm, leaving a bit of extra space to add a gasket if needed (I used Teflon tape, but simple silicone would work as well).
