dishwasher impeller

This is a replacement for a Maytag type dishwasher wash/rinse impeller. It is to be printed in 2 parts, top & bottom, and then crazy glued together. Best to print it using PETG because it gets hot inside the dishwasher and I don't think PLA would hold up. If the keyed hole doesn't quite fit your dishwasher shaft then do what I did. I used a small heat gun to slightly soften the PETG at the keyed area and then pushed it onto the shaft of the dishwasher. Then I removed it and now it has the exact size.

I have this in my dishwasher now and so far it has survived a couple of heavy cycles.

(Working since September 16 2022. Still working now September 30 2022.)
