A simple sieve/strainer to keep solids from going down your gutter pipes. I couldn't find one that fit my gutters, so I made this one. Maybe it will work for you too.

I recommend printing with PETG or other filament that can withstand outdoor temperatures and direct exposure to sunlight.

The attach picture is from my first version that didn't have holes designed into the top. I drilled all the holes in that picture. The profile attached has the holes designed in.

I also recommend cleaning frequently as it can block water from going down if it has strained enough out.
