This is the lower wash arm nut for the Model #58714402400 Kenmore dishwasher. The part number for this nut is #5304461011. This part was discontinued by the manufacturer and I was unable to find one anywhere.
The nut in my dishwasher cracked and broken into two pieces. I was able to temporarily superglue it together in order to obtain measurements.
Since it was for a dishwasher I was worried about the heat and bacteria. So, I ordered some PETG. This was my first PETG print. It is a little different than working with PLA. Initially, I had some trouble getting the first layer to adhere to the print bed. After doing a little research and tweaking, I was able to find the optimal settings for printing with PETG on my Ender 3 Pro. I have included the settings so you can refer to them.
