Hygrometer Holder For Filament Drybox

This is my take on holding of a hygrometer in a sealed cereal storage container. I agree with others that the hygrometer should be as close to the top of the container as possible and this is fruit (though minute) of that effort.

This fits into the snap lid without fasteners. However, if it does not hold firmly I plan to hot glue in place - if needed.

EDIT: I did need to use hot glue. Feel free to scale as needed, but I chose to keep as designed.
