Solid main drain cover?

Does anyone have a solid maindrain cover for a sealed off maindrain, or have fabricated one? I haven't found one on the googles, yet.

When my pool was built the main drain was purposely capped off from the outside.
However, the installer still put on a normal maindrain cover. Debris and dirt can hide under this cover in the maindrain niche becoming a breeding ground for nastiness. Vacuuming doesn't effectively clean it, so once a month I take the cover off and use the vacuum hose to clean it out.

Well not *all* of 2020 is terrible...... find your local 3D printing club and have them make you a solid one going off the original.
