Dehumidifier for 3D printer

I was a bit worried that my 3D printer filament might be getting a little damp as sometimes a reel can last many weeks. So I decided to build this little dehumidifier that would look tidy inside my DaVincy Jr 1.0. It looks nice in there and is clipped onto the frame so doesn't move around or fall over.

I used some water-absorbing crystals I bought at a local hardware store. The PLA may not be that suitable for this due to the chemicals in the crystals and the water that will build up. I could have just varnished the inside but I decided it would be nice to put a plastic crystal holder inside instead.

To accomplish that I made the box the right size for a large Tic-Tac mint box, which I cut to fit with a cutout for the front air flow. The OpenSCAD file is included so that you can change the design to suit other ways of holding crystals, as well as to let you customise (or remove) the 20x20mm section frame clip.

If you like this design, why not buy me a coffee:
