RV Shower Strainer

This is a shower strainer for a Hymer RV. l made this model for someone on Facebook. I don't own an RV or know much else about it. Photo of original part is posted.

Should print without supports on top surface (as pictured / modeled).

Dimensions of revolve cross-section are shown. Fillets were added after the revolve. Also added small fillet to base (top?) to mitigate "elephant's foot).

Feel free to request changes for fit and function. For example I considered making a second piece that snaps on to function as the "handle" in the original part.
