This is a stackable humidifier pack holder for Boveda style packs. Can be used for cigars, tea, cannabis, and more. Print with no perimeters, no top or bottom layers. Set the infill to somewhere between 30 and 70% with an infill type like gyroid that is stable by itself but lets air through easily in all directions.
This was designed for the 60 gram Boveda packs, but can be easily scaled for any size humidity control pack.
