Finally fixed the hole size! Should fit the usual Amazon round hygrometer perfectly now. 

I needed a nice portable humidor/storage case for my cigars so I modified this awesome model I found on Printables. I modified it to fit most cigar sizes and to include a hygrometer to keep an eye on the humidity to ensure the cigars stay at the optimal humidity and temperature. I also increased the gasket thickness to get a better seal. I printed mine out of PLA but PETG might be a better suited to handle the occasional drop.

I used this hygrometer found on Amazon, its pretty cheap, same ones used in many models meant to hold them in the AMS units.
