Summary

I needed a way to attach an aftermarket skimmer to my pool because these pools don't come with them. You can attach a 1.5" hose to the larger end, (friction fit for me because it's on the suction side of the pump) and the small end runs through the nipple built into the side of the pool, and snug up a hose clamp on the outside. It worked better than I hoped. PETG or better for this print. I wouldn't use PLA unless it's an emergency.
