Dishwasher Air Gap Drain

Edit 5-15-23: My models mistakenly had the drain chute about 4mm shorter than the design it was derived from, which works for my sink but likely not others. Posting original length (OL) versions.

Recreated because I was having issues with the original mesh. Conical on the inside, domed the outside top so that it will print without supports.

Given the nature of the design, there is no real seal formed. I used a ring of plumber's putty on the inside bottom edge to eliminate leakage.
