Filament Drying Box

Are you sick of drying your spools on top of your printer bed in a ugly cardboard box?
Me too so I created this simple box with the purpose of drying filament spools on my printer bed.

The box has 200x200x100mm dimensions, you can adjust to your spool diameter, i suggest going for 225x225x100.

The box has been designed with convection in mind so one of the sides has a 8mm in height opening so cold air can come in and some holes on top so hot humid air can escape.

I didn´t test it yet but i don´t see why it won't perform as good as the Cardboard box method....
