The airlock is a pretty clever tool, at least we think so. Therefore, it deserves to be accompanied by some pretty clever 3D printed friends. The parts are posted on Thingiverse - an awesome portal for sharing 3D print files. We have printed them all on our Formlabs 3D printers and can confirm that they work well and deliver on their purpose. Here are links to the different parts: carboy / bucket holder, SSBrewtech unitank leg mount and when not in use holder.
