Extremely Basic Tub / Pool Drain

I just made this part for a guy asking for help on the engineering board. You'll have to drill holes in it or edit it in TinkerCAD to get it how you want it.

It’s a 1.5” hollow cylinder with a 2” diameter. There are threads on the outside, 12 per inch. Sitting on top of it is a circular piece. It’s 3.5” in diameter and 2 mm thick.
