Description
I have lots of tobacco leaf I store for rolling cigars and pipes. I needed a better way to control the humidity the leaf is exposed to. This not not really a 3D printed project, but I wanted to keep track of some notes and links for future reference.

I have started to accumulate both home grown and online purchased leaf that has been stored in various plastic bags in cardboard boxes. I can go from high mold risk to desert dry. The solution I am documenting here is a gasketed storage tote with a 2-way humidification device. I also added in some humidity meters, and my 3D printed cigar humidifier. See the main page for this model for additional details: https://www.thingiverse.com/thing:6783663
Temperature is still going to need to be maintained, but the large humidifier pack combined with the 3D printed humidifier has brought leaf case up and maintained a stable RH. I would not store leaf without a 2-way humidifier pack, as I think humidity levels in this sealed tote could get too high.
