Hi, I love the look of your engine and the smoke effect is great. I was actually looking into doing this after I discovered these ultrasonic humidifier devices and was happy to find someone else had tried them out for this and they worked well. I was wondering if you have the 3d print files publicly available. I understand if not as it looks like a lot of work went into it, would just be very useful to me trying to make my own version. Anyway great post, it convinced me to finally make a eurobricks account after lurking for a while specifically to ask this question.
