Main Water Cover

In short, the cover for my main water broke (the green thing in the picture). It is plastic and about 30 years old. Buying a new one is about $20 or so. So I am just designing my own, and saving the money.

I'm printing what I got uploaded here. But I also have the fusion 360 file for if you want to change anything like the size.

It should be noted, I kept all the holes below a quarter inch size. Mice can get in quarter inch size holes. And obviously, you don't want to deal with a snake.
