I have an Intex 24 foot round swimming pool that I installed a larger Hayward 1 Horsepower DE filter and pump on. The factory attachments weren't designed for hooking up a vacuum hose to, so I went and designed this adapter that screws onto the water inlet line that sends water out to the pump. This will fit a standard 1.5" pool vacuum hose. Enjoy!

Printed this in Polycarbonate for the weather and chemical resistance, but PETG works as well - my PETG print lasted about 2 years and then the threads came apart. I wouldn't recommend PLA for this as pool chemicals would damage it quickly.
