Venturi Nozzle12mm Hose Fixed by Downunder35m on SketchfabĪnd last but not least for those people who don't like hose clamps: Here is one directly for a standard 12mm garden hose: If you have a good pump on your fish tank it might be a nice addition to get a strong current and more air in your tank. The nozzle might still work if using outside the water but the full potential only comes under water. Please note that this design is meant to be used submerged! The barbed fitting is for a hose with an inner diameter of 10mm, like found for most cheap shower adapters for the bath tub. No support required but a wide brim is recommended so the air vent will stay on the build plate. ABS is prefered but PLA should work the same. For the printing I recommend a fine nozzle and 2 perimeters, 40% infill. Venturi Nozzle 10mm Hose by Downunder35m on Sketchfab I am not responsible for any damages you cause to yourself or others if you don't use the nozzle as intended! Here you can see it in action on a 1.25L soda bottle:

Basically for everything that needs decent suction.ĭisclaimer: I only provide the files and assume you know what you do with the nozzle! I am not responsible if your printed nozzle fails due to poor print quality. Of course to make bubbles in your bath ) If you need a bit of vacuum, for example to degass resin, you can do this not without an expensive pump. After a few not so good ones I now have a little nozzle that is strong enough to deflate a soda bottle, don't have a vacuum gauge at hand but it really sucks enough to feel it on your finger when closing the air vent. I wanted something that not only sucks well (sorry for the bad joke!) but also provides a lot of pressure on the outlet so the bubbles are dispersed properly. There are quite a few 3D models available for Venturi systems but they are either meant for the use with compressed air or need far too much water. If you have no clue what that is check Wikipedia. No, I decided to make a little venturi nozzle! Take a hose from the compressor instead? ) My little niece complained about her bubble bath not having enough bubbles! So what can the good uncle do about it? Add an air pump and bubble stone? - Takes far too long.

Update: : Added two models for the use on a compressor instead of using water.
