No more knots in tubes :-)! This quick print easily regulates water and air flow with fine adjustments possible from free flow to a veery slow dribble on to a complete stop.

My tubes have an outer diam. of about 5-6 mm but it will work with slightly different measures too. Works with relatively hard and soft type of tubes.

It's an easy print of about an hour. I printed all the parts in PLA, 0.3 mm layer, 30% Infill. 

Print the main body vertically with the “stop-bar” facing up. Also the pin I printed vertically and it turned out well, the wheel of course laying on it's side. 

To assemble you might want to use something to carefully hammer in the pin into the wheel. Then insert the wheel into the main body and finally insert the tube. With the tube inserted, the wheel will not fall out. 

When in use, it is preferable that the close position is facing downwards so that gravity can't unwillingly open the valve.
