Description
I built this model in Tinkercad as a result of a problem I had. Our old sink was a two hole 8 inch deep sink. Our new sink was a 10" deep single hole sink. There was not enough fall in the pipes to drain properly and a standard tailpiece with dishwasher connection still didn't give enough room. I built this piece to be able to get the P trap as high as possible and still be able to connect a dishwasher. You will have to purchase the slip joint nut and tailpiece washer for a 1 ½" under sink drain. You will also need to pause your print at about layer 100 to place the nut to make it captive. I printed this in PLA to test it, but you will likely need to use PETG or some material that is more impermeable to water and kitchen chemicals. This saved me from have to tear into the wall behind my new cabinet and lower the Tee in the wall, maybe it will help you.
