DIY screen top parts?

[Enderg60]

Im planning some screen tops for my tanks, I found the outside corners which work great but I was wondering what else was out there.

Does anyone have anything made up for feed doors that integrate with the screen frame?

Anything that can go around a seaswirl? Anything for a mount for a ehiem auto feeder?

You can do cut out corners with the window parts; you just need to trim them a little so they fit backwards. Of course big interior corners like for a feed door cause the actual screen part to be impossible to tighten.
