Week 3: Finding the right fit

From moment one we were experiencing problems with our valve fittings. Turns out: our valves were to big for our fingers to handle. In the picture below you can see our first type of valve rupturing one of our fingers.

But then christmas came early! Our expert Rob Scharff supplied us with a bunch of different kind of valves we could test. He even tossed in some glue to make the seal as airtight as possible.

Below you can see the smallest valves glued to test prints. It turns out that not only the material does not rupture, but the seal itself is also completely airtight. This leads to most of the air leaking through the valves themselves. Turns out it’s not all about size on this one.
