Drying Filament

[arvidj]

I admit to taking the easy way out (i.e did not look for the absolute best deal on the internet)

Amazon searches for ... rechargeable silica beads, then organza bags, and finally humidity indicator card.

You may want to google "indicating rechargeable silica beads" and decide what color you want ... or no color at all. There may be issues with toxicity if you are into that type of thing.
