Filament storage has turned into a monster, given the need for dryness.  

No, you can't store filament in open air like a gootube star dramatizes.  Gootube stars can afford to buy new filament every week.  Even PLA absorbs water & dies over time.

Most animals seem to store it in a plastic bin & access it from above.  The problem is the horizontal space required for that is $1000/sq ft.  Vertical storage is more economical.
