Well, here’s a mod that I started a few years back. While it’s been pretty much done, I haven’t finalized anything. I did have some acrylic window in there, but I’d put it in before I put in my fan. I ended up ripping that out and using some fly mesh. Eventually, I may put something better in, but for now, it’s fine.
Around 12" x 13". It’s taped on from the back, and since it wasn’t there to fit precisely in the window, I just cut a section from the roll and then trimmed it as needed.
