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.
