I recently needed to print a replacement door for the Whirlpool dishwasher’s detergent dispenser. This post details my adventure, which took three prints to get it right.

For the short version of the story, see All3DP’s brief page on how to stop ABS print warping. For the whole story, read on.

LATE UPDATE: Prusa’s excellent post on food safe printing basically says ABS = bad and that it’s really hard to make a safe 3D print regardless of the type of filament. In my opinion, you’re probably better off buying the Whirlpool replacement part rather than printing something that will harbor bacteria and fungi.
