Dehumidifier - small for filament box (Calcium Chloride)
thingiverse
I wanted a way to keep my filament spool dry - just for show, no need to print the actual bottle. This is a calcium chloride de-humidifier that fits onto an existing bottle we were about to throw away (it's probably http://www.pbpackaging.com.au/ProductsDetail.aspx?enc=SQ3n08Ed%2bhEtNGGLkOY2WS9QmiYIM57WaxG1Qw%3d%3d). I'm using a common 260ml bottle, the kind used for vitamins in Australia - it's small enough to fit into my spool holder box. The basket hangs perfectly in the mouth of the bottle and screws on tightly. It gets filled with Calcium Chloride (I think I bought Damprid from Bunnings last time).
