irrigation system attachment for 7mm diameter tube.

This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/1Cvq199F8dl

yay. not sure if the design works yet, so if you print it, good luck.

meant for 7.5 mm diameter tube drip irrigation system but i suppose you could scale some of the parts from tinkercad yourself.
