My Dolphin pool cleaner threw a blade off the impeller, which made it unable to stick to walls and climb. This is a partial remix of a similar shape and blade impeller. I've included the complete model, as well as the keyed shaft and blades separately. I'm not 100% sure this will fit other models than the Nautilus Dolphin CC, so you can size the separate shaft and impeller blades to match your model. And yes, it works!

Note in the image, I had an earlier version installed in my pool cleaner. The version shown next to the broken OEM part is now installed as it is a better match for the overall shape and blade layout..

Design was done in Tinkercad, which is more than enough for resizing the height or diameter of the impeller.
