Aquarium - Brine Shrimp Hatchery (Modular)

thingiverse

A modular brine shrimp hatchery: clip multiple units together and run them with a single air pump with a line splitter for a constant supply of fresh brine shrimp. the base is large enough to accommodate 2L soda bottles when multiple units are joined. The unit has 2 air line connections; one for the air supply and the second to siphon the brine shrimp out without having to disconnect the pump (just turn it off). Print Settings: Recommend printing with 3+ shells and a layer height =/<0.15 to make sure the layers are air/water tight. Post Printing: A garden hose o-ring will be required to guarantee no leaks from the bottle. If printing in PETG, I recommend passing a pipe cleaner through the air passage to remove strings and keep brine shrimp from getting hung up. On safety and longevity: Both PLA and PETG plastics are generally considered food safe but some of the dyes and additives might not be, so I use "natural" colour to be safe. I recommend printing in PETG long term since PLA is biodegradable and the presence of heat and water will cause it to break down (though from all accounts I've read, it will still last for over a year).
