Silica gel Universal spool box

Did you ever struggle with wet filament? It's hard to print materials like PETG, CPE or Nylons and even harder to store them in a dry environment. Easiest is to buy a box of color-changing silica gel, print a few containers and slide it inside a spool and let the magic work. Even better is to vacuum seal your spool inside a bag and I promise, that you'll never have to deal with a wet spool of the material.

I made a simple container with wents small enough to prevent falling little balls of silica gel out of it. Also, there are enough holes to suck humidity out of your filament. Because not every spool has the same inside diameter and not every printer is accurate I made curved thin walls that act as a spring. It doesn't matter if you print it in PLA or PETG, both material works flawlessly. I made it for dual extruder, but you can print it without the text and the result is also amazing.

When your silica gel change color from original to darker you just take off the lid, dry it inside the oven, in a food dehydrator or on the print bed and you can use it again. Just give it a try and you'll see if it suits your needs.

Happy printing
