I had wondered about this as well and think it’s an awesome idea. Combo of good dry storage and printing from an active dry box seem to make this a non issue for me, but I like the idea. Maybe a coil of ptfe tubing that is fenestrated and with dessicant, a bit of heat and proper fan could do this quickly with minimal resistance. I bet its possible. I paid $45 I think for my firefly box. To me, I would place A value of about $90 on a system that did this well.
