Airlift pump / Luftheber

thingiverse

I've drawn it specifically for my "FLUVAL Spec 5 Nano 21," but the design should easily adapt to nearly any nano aquarium. - v3: This version is thinner walled and prints faster. Unfortunately, performance remains the same, but it's much louder - a constant gargling noise can be heard. - v4: Being thicker-walled, this version takes longer to print, but it's extremely quiet with no gargling sound. I currently use this one because my aquarium is on my desk. - v5b: This version is slightly modified from v4 to make it printable without support. - v6: A new and 3D printing optimized version has been designed. Printing time has been reduced by half. p.s. I came across something interesting - the airlift pump, which can be found on Wikipedia (https://en.wikipedia.org/wiki/Airlift_pump). I use a Piezo Mini Air Pump ("Cambani Mini Piezo Air Pump For Fish Tanks") in my aquarium setup.
