WHDTS 20mm 113KHz Ultrasonic Atomizer - Case

thingiverse

This project requires a widely available ultrasonic-atomizer/humidifier that's easily accessible. These units usually come as just a printed circuit board (PCB) with a 'humidifier disc' attached by wires. This case simply encloses the electronics, providing a path for the wires and two cut-outs to access the 12v power plug and on/off switch. The setup will be used to create a "Misting Chamber" that produces a chemical fog of 90% isopropyl alcohol or Acetone. These atomized chemicals are used in the enclosed chamber to smooth out 3d printer parts. Since the atomizer pulls from a small reservoir, only tiny amounts of either chemical are present, minimizing the fire hazard. I'll post the full setup along with my results later. At this point, I'm sharing this small case with the understanding that it will be used for "distilled water" fogs. Don't experiment with 90% isopropyl alcohol or Acetone near electricity!
