I really like the filament concept. Do you leave the filament hanging all the time? The reason I ask is that I read all the time about filament absorbing moisture and contributing to jams and pops in the print. I've always kept my filament in nearly zero humidity containers and never leave it out when not printing. I don't do this based on any prior experience. I do it only because of what I read. It would be nice to know if some of that fear-mongering about moisture was misleading.

Just curious how you deal with it and what problems, if any, you've had.
