Thruster Shrouds and Rice or Kort Nozzle


I’m not having much luck. But I am wondering if anybody has already made up a file that can be thrown into a 3d printer that will cover the thrusters for a more aerodynamic flow. (but still allow water to flow into the motor)
Even better if it includes a Kort Rice Nozzle.

I’m finding this for other motor options (mostly for the bilge pumps). I would like to use the OPEN ROV thrusters though.


This may not be exactly what you are looking for but it is an idea I came up with to improve flow in my hybrid. You can find the full file in my “Rover 1” post


Thank you.
I did see those, but it’s not exactly what I am looking for. I do appreciate your help though.
