Smart Dryer Box

Simple to print Dryer Box for your filaments. I used a hotend as heating element. Probably not the best solution, but enough to get about 40°. If you experiment with your heating system, share it with us! Component: -3.3V relays -Nodemcu as microcontroller: you can configure it with your WiFi for remote control (I used Blynk App) -Stepdown 12-5V -12V heating element -Display -DHT11 as temperature and humidity sensor -5V fan to spread the heat
