i bought a amazon dryer if you want a link holds 2 rolls and filament and can print from it, takes about 4hrs to dry out pla, scaling in temps and ranges for diff filaments, as for storage, go down to your local ace hardware or similar and get the 21 cup storage bins for dry food storage, their like 10 bucks ea instead of 20 on amazon
for dessicant i went to the auto parts store and bought those car dehumidfier things, lots of gel dessicant for like 10 bucks or so and a handy container to hold all the water it collects
Filament dryer $60 usd, https://www.amazon.com/dp/B09BBDG5MK/ref=cm_sw_em_r_mt_dp_TRFXAH6C7VYVZS7FK990?_encoding=UTF8&psc=1.
