This clip broke on my dishwasher. It prevents the top rack from leaving the dishwasher. First I modeled and printed the steel railing to make sure the original clip would fit in my modeled rail. Then I designed a replacement clip that was easily 3D printable.
I printed this in Polymaker ASA which can withstand the dishwasher hot washes and drying cycles.
Printed as oriented for strength. Needs supports but no one will ever see where the supports touch the part.
After three months of daily dishwasher use it is still functioning as designed.
Here is the replacement part: https://www.amazon.com/WPW10195622-Dishwasher-Dishrack-Stop-Clip/dp/B09P8D54XJ/
