About this model

I needed an air gap for my Water Softener. I couldn't find anywhere local to purchase one and didn't want to pay $30+ to order one online (and chance it not working). Figured I would share. I would recommend printing with PETG (what I chose to use) or ABS. PLA will break down from the salt water. You can then use whatever 1/2" MIP/NPT threaded adapter to attach the desired drain hose. Print with the thread side facing the build plate.
