DIY Filament Dryer 3D Printed Parts  

These are the 3D printed parts I designed for my DIY filament dryer project.  

The dryer is built from a 4L food container and uses a heater, fan, and a NodeMCU board for control to warm up the filament in an attempt to dry it from moisture.  

I printed them in PETG for better heat resistance but it will be better if printed with ABS or PEEK if you have the ability to do so.
