Desiccant Container (fits inside spool)

prusaprinters

<p>I live in a climate with very wet winters, so I have to store most of my filament with desiccant, and I designed this container to fit all the different spools I use. I put the open column in the center to both increase the surface area and reduce the amount of desiccant in the container. I also wanted to be able to see if the desiccant is dry (i.e. changed color), so I made sure to keep the mesh sufficiently open and provide enough exposed surface for an easy visual check.</p><p>My prefered long term storage method is to buy color changing desiccant in quantity, fill up one of these containers, and then vacuum seal the filament and desiccant in a sous vide bag (as shown here).</p><figure class="image"><img src="https://media.prusaprinters.org/media/prints/62231/rich_content/8c822e7b-e424-4a1f-b784-182e49c9bdf8/pxl_20210402_144002377.jpg#%7B%22uuid%22%3A%227b9ac932-dd3c-4e8b-9189-2e859a454edb%22%2C%22w%22%3A4032%2C%22h%22%3A3024%7D"></figure><p>I've uploaded the STLs, but you should print from desiccant_container.3mf, because the screen portions rely on specific infill settings. The 3MF has eight containers, which will fit the bed of a Prusa MK3 or a Creality Ender 3, but you can just as easily reduce or increase that depending on your need and bed size.</p><p>The included 3MF is for PLA, and the container isn't really not designed to be printed in any other material. Any brand should be fine; I would just suggest using a natural/clear roll with no special additives. I just throw these containers as-is into my dehydrator when I need to dry them. After a few drying cycles the PLA seems to naturally anneal, making it capable of withstanding even higher temperatures.</p><p>If you want to change the settings, printing at .2mm layer height on a .4mm nozzle (draft settings work fine). The threads don't seem to work at thicker layer heights. It's probably best not to use larger nozzles, because the infill on the screens assumes a .4mm nozzle (extrusion width explicitly set to .38mm), although I haven't actually tried other nozzle sizes.</p><p>&nbsp;</p>
