I was looking for a desiccant storage solution for my spools of filament. After experimenting with many different ideas I landed on this concept. Inspired by some other designs this container holds desiccant packets in a cylinder that fits inside a spool core.
Why design for packets? The drying temp of the desiccant is higher than the deformation temperature of PLA. As a result, if I used raw beads I couldn't dry them in the printed spool core and would have to scoop the loose beads in and out of the cores to dry them. The packets were easier for me, I just dump them on the cookie sheet, dry away, then drop them back in the cylinder. I found 50g packets fit just nicely in the 70mm and 60mm cylinders, but you can use smaller packets.
Since I just use Ziploc bags and they are prone to holes and tears. I like to use the little EEEkit hygrometers you can get from Amazon. Its much easier for me to see the dryness of the air than the color changing desiccants. One of the top covers pro
