I have a nice tiny ultrasonic humidifier which has several issues:
- it is designed to accept PET bottles only
- it is almost impossible to clean the vapor head properly
- if turned on it will illuminate a disgusting strong blue light thru the original transparent acrylic vapor head
I have modeled the original vapor head (slightly modified to make it printable w/o supports) so you can print a new, non-transparent one.
As I don't have any PET bottles here at home - but have several Sodastream tanks - I have also created a Sodastream to PET bottle converter.
