Customizable Drain or Vent Cover

I saw someone on Reddit explaining the steps they took to build a one off drain cover, and then they needed to use cutters to cut out part of it to allow a pipe to pass through. This got me to thinking that I could probably make a customizable/parametric version of such a thing to save people time in the future. This designer allows you to customize the size and shape (rectangle/circle/oval) of the overall cover, as well as the holes, and the optional cutout hole. You can also optionally have an outer ledge (probably more common for a vent cover than for a drain cover) and taper it if you want. You can also optionally taper the bottom sleeve, if that might help it fit better. The rectangular holes can be perfectly squared, or they can be rounded as in the picture. You can change the size of the holes, and the spacing between them. You can also control the thickness of the grate and of the sleeve. The example was printed in PLA, but you would probably want to use a different filament if
