This is a floor drain cover for a 2" opening. It has both top and side drainage features to keep that water flowing where it belongs!

Notes
I designed this model in OpenSCAD and it's fully parameterized. If you'd like a simple modification (e.g., drain or cover size, height, etc.), send me some measurements and I'll see what I can do.
