Need 5in 3bladed Props with Ring that encircles the propellers

[107Pilot234567]

I have been searching and searching. Does anyone know of such a product? I have found very small ringed propellers but nothing of this size.
Is there a manufacturer that will make these for me?

This is a project for wounded warriors. Your help is much appreciated.

Is the purpose of "ring" intended to replace or act like a "prop guard?"

I do not think you will find something like this for a Drone whose motors turn very fast. An item like this would be very difficult (expensive) to balance. And after dong several Deep Google Searches, you will probably only find something like this on a "low RPM" toy…

Good Luck!
