The upper rack wheels of my parents' dishwasher were crumbling after 15 or so years. Rather than spend the $46 per wheel that most places wanted, I decided to model the wheel and print them myself. I haven't tested this wheel on any other models, but fits their Samsung dishwasher (dw80f600uts) quite well.
