More of my fluid management designs I've made a number of these little tees for various test builds when I didn't have and/or forgot to order real tees (or I guess Ys in this case, but I tend to call all two-way splitters 'tees' I guess ¯_(ツ)_/¯). I have printed and successfully used many of these printed from a handful of resin materials BUT please keep in mind that resin materials are extremely unstable and not safe for contact with anything food related!! I've only used these for test setups, not for anything that is going to any 'real' plants or the like. If anyone does know of a path to getting foodsafe parts from resin, I would love to hear about it!

But, if you're looking for an option to split some 3/16 tubing and have a way to print it to your needed safety standard...here ya go :)
