[Daryll Strauss'] dishwasher had some problems that he traced to a worn out part on the upper spinning arm. The hackerspace he belongs to has a Makerbot and he though this would be the perfect opportunity to print his own replacement part. He picked up some inexpensive digital calipers and set to work*mapping*out the dimensions of the broken piece. He took his hand-drawn cross section and built a replica part in Blender. Once he had it just right he generated the g-code and printed the part. His replacement works very well, and it’s a bit thicker (by design) than the original so hopefully that means it will hold up longer.
