If you have any question with this please leave a comment or send me a message and I will do my best to answer you as soon as I can.  I have had rolls in my box for over 2 years that printed just great when I got to using them.  If you build this please give me a boost.  This was printed on an ender 3 pro and was designed for it when I had it.  The dry box has been in use for almost 3 years and works amazingly well.

Printer tower with 10 roll filament dryer storage!
This is a real project that will make your setup clean and keep your filament ready to run at any time. The files that need multiple prints of have been labelled as such.

Filament Dryer Storage:

The most effect way I have found to control the humidity is using Home Assistant. I use a zigbee temp/rh sensor to power on a zigbee smart switch controlling the power to the heater and blower inside of the dryer. You can use an arduino or pi but I found the relays are more prone to break than the smart switch. I also prefer being able to see a running graph of how it preformed over the last week.

• 20%+ infill
• supports needed on parts with overhangs
• PETG or high temp material as it will get hot inside of the dryer

I will do what I can to answer any questions you may have about this. My dryer has been in use for over 2 years and I keep my humidity around 12%-15%.
