Fume - The (Knockoff) Good Habit

THIS MUST BE PRINTED IN PETG SINCE SOME ESSENTIAL OILS CAN DISSOLVE OTHER PLASTICS.  Similarly, the wick has to be 100% cotton or at the very least insoluble in the oils you choose to use.  It's a good idea to test your materials by leaving a few drops of your oil(s) on your PETG and wick for a while to make sure the oil(s) doesn't react.

This is a 3D printable knockoff of the Füm, a vaping/cigarette alternative that swaps the nicotine for essential oils.  There are no electronics as all the vaporization is done passively.

Function is pretty much the same as the original, but avoids the ~$100 entry cost and the need to buy official oil cartridges.  All you need to do once you've printed it out is stuff the core with cotton balls or any other source of pure cotton that you can jam in there to act as a wick for the oils.  There are different caps with different sized holes to tune how much drag there is when taking a hit, I like the one without a hole since there's a lot of drag with the air having to pass through the threads.

All the other warnings besides the PETG thing are covered pretty well on the Füm website, so go look at that just in case before you try making my version.

As far as print setup goes, use the models as oriented and use organic supports set to “For support enforcers only” since I've got enforcers painted on for you.
