Hey man, I saw everyone talking about cleaning the edges up, and I just thought I would thrown in my 2 cents. If it were me, I would get some auto edge trim to finish the screen. Far easier and much less work than filing it to make it perfect. Maybe just trim it a bit to make the edges more square, throw on some edge trim, and it should look great! Some 1/32 edge trim should be the size you need I would think for that. They also make it completely smooth with no metal inside, which is probably what you want. I just linked a quick search on amazon above to show you what I was talking about in case you hadn't seen it before. Should be able to pick some up from any auto parts store, though maybe not the 1/32 stuff.
