This 3D print demands supplementary components. Peruse updated images depicting wiring up control switch setup. Wiring instructions: Brown (-) and Green (+) from Ultrasonic mister are required. Green wire connects to switch, emerges as red wire, joins back to Step Down DC-DC Module (+IN). Brown goes directly to -IN of Step Down module. Module features 2 solder holes per input, simplifying connection of inputs (+IN and -IN) back out to humidifier (after the switch), making switch simply the ON/OFF control for everything. Adjust to correct voltage (+OUT and -OUT) using voltmeter. Connect +OUT and -OUT to 30mm 12V DC Fan. Note: - IN and -OUT serve as identical connections. Congratulations are in order upon completion! Sealing your print, making it watertight is a must. Always a challenge for any prints. Access Expert menu on Cura, Open expert settings (CTRL-E), increase infill overlap to 50%, attempt to raise infill, if possible, print 100%. With ABS, brush the inside with pure acetone. With PLA, brush with clear acrylic, e.g. Tamiya X-22, clear gloss coat. BOM includes: 1) Ultrasonic Atomiser (Search ebay for ultrasonic mist fogger, it's the black plastic version, 36mm diameter) 2) 30mm Fan (4 x 18mm screw for attachment) 3) 2 (height) x 3 (diameter) mm neodymium magnets (Search ebay) 4) A Step down power converter module, (http://www.icstation.com/step-down-module-power-supply-p-2734.html) 5) Rectangle flashlight push button switch (http://www.ebay.co.uk/itm/3-Pcs-Rectangle-Flashlight-Latching-Push-Button-Switch-AC-250V-1-5A-/121759137697?hash=item1c5968ffa1:g:N3UAAOSwEetV9dkz) Either a 'coke' PET bottle or Kikkoman Soy Sauce classic bottle (looks nicer and it's glass) can be used. The ultrasonic atomiser requires 18~24V, any 19V laptop adapter can be utilized for this purpose, old Dell and Acer laptops often use regular 2.5mm DC plug. The fan blower speed can be adjusted with the voltage step down module. The humidifier blower is held in place simply with magnets superglued into inserts.
