Smoke Testing 120mm Case Fan Conversion to Centrifugal Compressor | Shorts

Just a short test/demo of an old (but continuously improved) 3D Printed compressor design I originally posted to Thingiverse back in 2018-ish. STLs are here: www.thingiverse.com/thing:295...
I use a pair of these to provide remote cooling to the hot end and layer cooling ducts on my Kossel's print head. It's a fair bit of trouble just to get some air through a hose, but it's also quieter than a blower-type design for the same airflow ... and I like my quiet!
If you want NOISE and boost, though, I also made this monster of a regenerative compressor: • 3D Printed Regenerativ...

I cant seem to figure out how to power this from the wall. I would need it to ventilate my Printer enclosure. Could you possibly send me how you were able to power it. I dont think a battery would last the length of time it would take to Print. as you know it can take as long as 24 hours or longer. Is there a way to connect the fan to a general home 110v outlet? Converters, or anything else i would need. Thanks, going to go ahead and print this.

It's just a 12V case fan, so any source of 12V DC will work as long as it can supply more current (amps) than the fan needs. I used an adjustable benchtop power supply for this video, but you could easily use a spare wall wart (just check to be sure it's 12V and more amps than the fan), or an old laptop power adapter, or even an old PC ATX power supply. Good luck!

You can use a 24v to 12v buck converter attached to the printer power supply to power te fan. There are a couple of unused +/- terminals on the power supply.

What do you think how many PSI can it make?

[@jamespray]

I don't have the tools to measure this. Probably not much, but a lot more than an axial fan of the same power.

@@freeytk390 If it's boost you're after, I did recently develop this regenerative compressor prototype that seems capable of at least a PSI of boost and sounds like an F-16 on the runway th-cam.com/video/YhsYaHobx-4/w-d-xo.html ... and in theory you could stack multiple units on the same shaft if you had a really beefy source of power =0
