Wheel for the track of an older Maytag Dishwasher. The Model number for the dish washer is MDC4000AWX,
Now getting close to 20 years old it out lasted the marriage for which it was a gift. A dish washer from back when there was a Maytag repair man sitting around with nothing to fix. Its a dishwasher where you can put an un-rinsed Pyrex lasagna pan in and it comes out spotless along with the rest of the load.
Divorced I am, but my dishes are as clean as ever without the bother of a wife.
Its only problem was a hose coupling leak due to the rubber breaking down. After the wheel broke, and the glue fix failed after 2 years... Its with pride I extended its life with the gift of a new wheel.

Included is the STL and the Solidworks file for those who have a real CAD program.
