Version 1 | DIY Heated Filament Dryer

I was looking through commercial filament dryers, they all have safety features and fun digital displays. They range from the $60-$120 range, depending on the level of safety. I wanted a bulk storage solution that also allowed me to heat the chamber for specific printing needs. I figured I was capable of creating a house fire in a box for at least twice the price range of anything commercial so I took a stab.

Requirements

• Heated chamber
  • PLA: 50C; PETG: 70C
• Multi-spool capacity
• Programmable display
• Ability to print from within the chamber

Parts List

• 12V 100W Heating Pad
• ESP32 with OLED Display
  • This included a LoRa chip for potential future IoT upgrades
• Cookie Cooling Rack (Example)
  • Find one for any price that matches the rough dimensions of your container
• Storage Bin (Example)
  • My next iteration will use a bin with thicker walls, the heat radiation on thin walls is significant
• (2) M12 (or 1/2″) Threaded Rod
• 28mm (M12) Bearings

Print List

• Thingiverse
  • Filament Roller
    • I cut this model in half and only used the top segment.
      The structure comes from the rod and storage bin interface.
