Microdrip Adapter 1/2" for drip irrigation system

I needed a 1/2" internal thread to micro drip hose adapter with two hose connections for my drip irigation system so I remixed https://www.thingiverse.com/thing:340931 using flanges to better accommodate my micro drip hoses. The two flanges have different size so they will hopefully fit most hoses made for micro drip irrigation systems.

There are four versions with 1-4 hose connections.
