filament keep dry box

I use the boxes to hold the filament dry during printing.
I can print PETG 24/7 without any problems.
Without this box i could only print PETG for 24 hours until it was too wet.

The following spool holders are fitting perfekt in the Box:

If the filament is wet, it should be dried and then packed in this box to keep it dry.
the box can't make it more dry.

If you want the filament to stay dry for a long time, I recommend using silicate desiccant. With the colored silicate desiccant you can keep an eye on the condition even without a hygrometer.

The silicate desiccant can lead to the formation of residues on the filament!
To avoid a clogged nozzle. I recommend using a filament filter:
