Replacement locking nut for the bottom spray arm of the AEG FFB83740PM dishwasher. The original nut (picture #2) is constructed in a way that's very weak, having a very small contact surface between the body and the threaded part. I tightened mine a tad too much and it snapped, so I designed this model that should be much sturdier.
This part might fit other dishwasher models as well, since a lot of these AEG/Electrolux dishwashers are similar. Let me know if it fits yours.
Print this in a temperature resistant material such as ABS/ASA. I used 50% infill and 5 perimeters and a 0.12mm layer height for my print and the threads worked fine.
Update 28.12.23, v2: The original part broke due to layer adhesion issues. I cut away a part from the original design to allow printing the part in an orientation which optimizes for part strength. At 0.12mm layer height, 10 walls and Arachne wall generation, the threads still print fine. Added a photo of the v2 printed in white ABS. Kept the pictures of v1 printed in black ABS for comparison.
