The humidifier has been completely redesigned to include the more expensive 30x30mm axial fan to use cheaper 40x40mm axial fans. This project was based on https://www.thingiverse.com/thing:768693 The nozzle is available in 3 different versions, which direct the steam in different directionsbe steered. 90 °, 180 ° and 270 ° to the bottle. You can find another nozzle at https://www.thingiverse.com/thing:4670885. There are two of these outlets on the side to direct the water vapor in two different directions at the same time. A PET bottle is used as a water reserve. The appropriate screw connection for the bottle. ------------------------------------------------------------------------------------- Since the ultrasonic atomizer is operated with 24V, you need a voltage regulator for the 12V fan used. Over time, you will probably have to replace the fan because the one with the Time no longer function properly (dust in the plain bearing). It is best to use an adjustable stepp down voltage regulator. I use the HW-613. This is a very small regulator with which a fixed voltage can be set using solder bridges. You can also regulate the voltage with a potentiometer and thus set the speed of the fan. But be careful not to exceed the voltage for the fan. A PET bottle is used as a water reserve. The appropriate screw connection for the bottle. What you need. 1) Ultrasonic nebulizer (search on ebay, Amazon Ali Express for ultrasonic nebulizer max 46mm diameter). If you use one with led's you should use the tray with a transparency Filament printing. Looks nicer. 2) 40x40mm axial fan plus screw fastening 3) A voltage regulator e.g. (Adjustable HW-613 step-down voltage regulator 2-24V) or (Fixed voltage regulator 12V) When shortening the cables from the ultrasonic nebulizer, brown (+) and green (-). If i saw it rightit doesn't matter what the polarization is. It should also be noted that the print should be 100% infill because of the tightness.
