I tought this was a great idea but ass soon as being installed, it was throwing more water out than in. Not really practical I guess :(

The thin cone version may work better for you. It is more efficient in higher pressure pipes.

Turbine Faucet Watersaver (Thin Cone Version)

The insert worked perfect! I love this thing. What a great idea.

I would love to get a version of this for my outdoor hose faucet with an garden hose thread.

Nice design. What filament do you recommend for this print?

Comments deleted.

nice!
for what is the second M24 stl file? _H = highresolution? higher then without _H?
thanx

Apps like Slic3r needs High density models. If you are using Cura, you don't need H files.

Thank you for this thing! Thumbs up to you!

for the realization did you use supports?

No supports needed.

Can i drink safely the water with this Turbine Faucet Watersaver?

Yes it would be completely safe.
Because the water is not sitting in the turbine. Every time you use it you flush away anything that might have built up over time.
No. The printer does not need to be food safe. At 400+ degrees Fahrenheit nothing coming off of a 3D printer is going to have any living organisms on it.

It depends on the filament you use. There are some safe filaments on the market for use in food.

The printer must also be food grade, I cringe whenever folks safety warnings stop at filament.

I am always wondering what could possible be not food safe about any 3d printer. Is it common for people to be spilling rotten steak juice on there printers and not cleaning it up? Are we supposed to be worried about lubricating oil from moving parts getting on the filliment as is passes through? If so, what kind of oil are people using on there printers moving parts? At what volume of ingestion of this oil does it take to become toxic? I don't know about you guys but the path my filament takes would be, through a Teflon liner, through a roller bearing and brass drive gear, through another Teflon liner, into a brass hot end and out. Which of these parts would be harmful to our health if the printer filament touched it? I really think the only thing we need to worry about with 3d printing and food safety is all the little crevasses between the layers for bacteria to get stuck and possibly poorly laminated layers. But then again, most people will not think much about finding a stick out of the woods, ram it through a hotdog weaner, slap it into a bun that has been laying on an unfinished wood top of a picnic table and devour it in 10 seconds flat.

The small micro gaps in the filament AFTER the 3D printing process can harbor viruses and bacteria. Clearly after coming out of a 190+C extruder there won't be any living germs, but that doesn't mean they won't form after sitting in a dark, damp faucet head for 3-4 weeks.

He asked about food safety of the PRINTER ;-)

I think it's more like, if you printed non-food-safe-filament with this printer before and some material of it sticks in it and it comes out when you print food-things, it could harm your health. But I think it should be enough to just use a separate set of throat and nozzle (and clean up the extruder). Correct me if I'm wrong please.

Brass contains lead as part of the alloy. Stainless steel is about the only food-safe nozzle that's manufactured for 3D printers.

Lead has a lower melting point than the other components of the alloy, so it tends to end up on the outermost layers of the boundaries of the grains of the material and the machining process further exacerbates this by smearing the lead as it's machined. This leads to more lead on the outside of the machined surfaces, increasing it's ability to leech out.

And seeing as how most every nozzle manufactured comes out of China, the amount of lead in their alloys is probably above the normal 2% or so.

I think it depends on the use case. If the plastic is used in a container where food will be in constant contact with it and for extended periods of time, then yes, many plastics are not safe. Pure PLA is relatively safer in comparison to ABS for example. ABS is not only unsafe, its particles taste and smell awful. I know, because sometimes I had to sand the printed items and I end up tasting some particulates in the air. :( Really bitter stuff! Now, back to the faucet aerator case, I think here the water is only momentarily in contact with the plastic. Plus any particulates would have been flushed away through time and use. However, I do agree with the possibility of bacterial contamination. And this is not just with the 3d printed aerators. Even with off the shelf bought aerators, we should be cautious about drinking water straight from the faucet. I remove the aerators and clean them at least once every year. I have to tell you the sight is not pretty. They are always full of visible mold, not to mention invisible bacteria. Therefore, I always filter and boil my water before drinking.

Love this design! Any idea on the stats of the water saver functionality? How many gallons/min or anything like that?

Not very empirical, but I do notice that my sink starts to fill with water after installing this whereas the drain had no problem keeping up with the basic aerator. Fun to look at if nothing else.

Thanks for the feedback!

This is not a flow limiter, this water saver works with low pressure. The water curtain is more efficient to rinse and wash. In this way you only need to open the tap from 15 to 30%. If you open the tap 100%, assuming that the pressure of your pipe is at least 2 kg / cm2, the water will have a centrifugal thrust. When the total mass is sufficient to pass the curtain, the water will collapse the drain.

This conclusion obtained by observation simply, I love talking about physics! I will be very grateful for any comments.

Thank you!

I love off the hop scientific discussion based more on experience and observation then on recorded numbers and memorized equations. What do you mean when you say, "When the total mass is sufficient to pass the curtain, the water will collapse the drain."?

I think he/she means that normally there is air in the drain pipe, so the water will pile up in the sink and will not immediately run into the drain. Eventually the weight of the water will be sufficient to push the air out of the drain pipe causing the water to "collapse" into the drain.

Same problem here, the file seems corrupted, not showing thread.

Try now,
It works on Cura

never mind print. The threads dont appear in the slicer! No amount of mesh repair helps... Any ideas?

What settings are you using?

Could not get this to thread into the tap. With the threads at the bottom, the first couple of threads came out a bit deformed and no amount of playing around would get the threads to screw in properly.
Not 100% sure I have my nozzle height set properly though.

Try to lower the flow. In any case, the first layer usually has more errors and needs to be corrected with a blade.

Also make sure to use full power on the cooling fan to keep the threading as sharp and accurate as possible, If possible, best to print without support.
