Upside Down Filament Extra Dry Box - Remix

Gathered together the design features from these projects that I found most useful when setting up my spool containers. These only require one hole be made in the box and minimal hardware, M10 coupler and 4x bearings.  Plus a Hydrometer and desicant of couse. Included are some modifications that improved these for my use (detailed below).  For more information on these designs, please visit the original creators using the links below.

Spool core desiccant box

By Kenny Z https://youtu.be/crZYk2DPatU

• Core Bin- *added an arm and handle with magnets (12 X 6mm and https://a.co/d/2JCdfRV and 16X4mm https://a.co/d/ctWrbxw) to manipulate the spool without opening the container or creating additional holes in the container. Changed the perforations to match the rest of the items. The original pattern kept failing for me.
• Core Bin Lid- *  Changed the perforations to match the rest of the items for the same reason above. 
• Core bin Clamp
