fan grate for fume extractor fan

so I bought a fume extractor for an upcoming resin printer that I will be getting and this fan went outside, which was through a window. The window does have a screen, but bugs are able to get in still, so I made this grate to keep potential bugs, if they come in between the screen. this is to prevent the bugs from crawling up into the pipe and into the room. It’s not perfect, some VERY tiny bugs, like gnats, could fly through but this is to prevent large bugs, like flies and mosquitoes. It lets airflow go through still but it will help with the bugs coming in.

no supports are necessary.
