Balloon Valve

thingiverse

A balloon valve which only lets air through one way. Probably known by many, i wanted to try and model one myself. Will only work with specific materials which have to be air-tight (kind of) I tried with ABS but it didn't seal properly. I may have to change a few Things in the model. If you're going to print it, (print in place) i'd be happy to hear some feedback.
