Not sure if it this part is used widespread in Siemens dish washer or not. It will not harm to publish the design anyway.Has to be printed in ABS, of course. It has a brim added which can be removed easliy by cutting and bending. With the brim it should stick well on the build platform. To keep dimensions and shape, use good cooling as if it would be PLA. I lowered bed temperature to <90° after a few layers, if the environment is too warm, the part will shrink too much and not fit anymore.
