A simple print to allow you to insert a small round hygrometer into the lid of a Chef's Path brand cereal container for use as a filament drybox. The insert fits inside the top lid seal (since you won't be pouring anything out from this opening anyway) and doesn't interfere with the airtight seal of the top lid. Fits snugly with friction and easy to remove. Print at 10% infill.
