Hose barb 13mm for Gardena microdrip sysytem

I designed a hose barb for the Gardena Micro-Drip system. It is an adapter from the 13 mm hose to a 1/8" female thread.

A 6 mm 1/8" push-in fitting can be installed in this thread, allowing you to connect a 6 mm hose to the dripper.

To make the connection properly watertight, a 10 x 1.5 mm O-ring can be fitted.

Finally, I dipped the hose barb in Dichtol Hydra to make the 3D print watertight as well.
