swe3tdave, August 2014 - i bought 2 rolls of abs from filaments4less.ca, both had so much humidity that it was impossible to print right out of the bag. So i bought 500g of desiccant, that's enough to keep a closet dry for a while, or so it said on the box... I took one roll and sealed it with the desiccant. It took an entire week to get enough of the water out before i could print. There was at least one ounce of water in there, probably more.
