About this 3D model

It prints best if you place the course threads on the bottom. I use my bathroom sink to refill my spa (Hot tub) and my fish tank water when I am cleaning it. This adapter will let me hook the cleaning hose to the sink so that when I fill the tank, I can get the water temperature adjusted correctly, without passing the trouble off to my tank heater of warming the water back up. I also use this to quickly fill my hot tub through a garden hose so that we do not have to wait as long for the water to heat back up after a change. This is the first design that I have posted here, and am open to comments and criticism.
