Water Aerator, no need for airstones or airpumps!

thingiverse

I'm creating a water aerator that leverages water pressure to draw in air, allowing water to enter through the bottom chamber and exit via two vents while pulling in air from the upper chamber. This eliminates the need for noisy air compressors, enabling users to build it using their 3D printers. It's particularly beneficial for individuals with aquariums or hydroponics setups in small apartments. The miniature version features a friction fit on standard garden hoses, whereas the full-size model has soda cap threads (PC1881) that accommodate custom 3D printed caps. The design is compatible with standard 20x20cm printers. I've primarily tested the miniature version and the larger version's threads so far. You can see the miniature in action here: https://youtu.be/ucByvDLCssU It does produce a bit of noise at the end of the input air hose, but I believe this issue can be resolved with a 3D printed muffler (I haven't modeled or tested one yet). I didn't notice as much noise when using unreinforced silicone tubing. This project is still a work in progress and feel free to remix it if you like the model or have any ideas for improvements. Update: As of July 16, 2020, I've tested the full-sized version, which works but won't function with the tap water pressures I previously used on the miniature. I'll need to conduct further tests using my homebrew pump to obtain accurate pressure and fluid measurements.
