Cereal box filament dryer

This print snugly fits onto the throat of the small lid of common 4L cereal containers. You can add super glue if your print is a loose fit. 

1. You can now easily add & remove desiccant to the container. 
2. Humidity drops much faster than those boxes that contain dessicant at the bottom of the container. (Why? Humid air is lighter than dry air & rises to the top, where it gets dried by the dessicant.)
3. Add a humidity meter to the box to monitor the humidity levels

You can add this print to existing cereal box filament dryer concept if you want to use the filament while it is inside the dryer box.
