Latch from Siemens dishwasher door catch mechanism
Latch part from Siemens dishwasher door catch mechanism.
The white component is the original broken component; note the piece missing from the 'beak'.
I recommend printing with the tail pointing down and back elevated from the platen with supports. This keeps the supports away from the functional faces. In any case, I found it important to orientate the model such that the lugs are printed as part of a long extrusion stroke, for strength. I naively tried printed with the lugs pointing north and south, and they immediately broke off on fitting into the catch mechanism.
Also recommend 100% fill for rigidity and strength. ABS may be a better option for longevity.
I used a linear fill pattern. 6 shells, and 6 top and bottom layers.
