1.5" o-ring to 1/2" pipe T fitting

Decided to add a solar heating loop to our pool. We're in TX so there's plenty of solar available! Figuring out how to get from the 1.5" o-ring sealed Intex hose fittings to something more standard was troublesome so I came up with this fitting. When printed in ABS it will acetone-glue to 1/2" PVC pipe just fine.

I may rework it soon to add a variable restriction downstream of the small outlet as this design doesn't provide enough pressure to properly prime my 50' loop of 1/2" irrigation tub
