Y-Splitter with 1/2" flange for use with 1/2" ID tubing. I noticed there wasn't a compatible splitter from 3Dponics so I decided to make my own.  I'm using this with 1/2"x5"/8" tubing and it works perfectly. Print Settings: No supports if oriented standing up like a Y Infill shouldn't make a big difference Enjoy! Designed with Onshape
