Hydrometer stand for Sterlite 20qt gasket box

The Sterlite 20qt gasket box is the best bang for the buck for filament dry storage.  I wanted to be able to see when the humidity was getting high and the desiccant needed recharging, so I bought a 12-pack of these humidistats and designed this stand to hold them.  The bottom of the stand is contoured to fit the Sterlite 20qt, so the humidistat stays upright and in the corner - easily visible and out of the way - even when you move the box around.
