(Enhanced) Filament dry box - heated, ventilated, Arduino or ESP8266 controlled

I ported the original arduino software by werner_rh for an Wemos D1 Mini because I wanted to monitor the drying sensor data with grafana. Therefor the sensor data is transmitted via mqtt an transered to influxdb using telegram. The improved code an configuration examples can be found in a branch at Werners github: https://github.com/werner-rh/drybox-control/tree/ESP8266-grafana

My git repository includes the kicad files as well. You have to solder the Wemos D1 Mini with the ESP8266 module facing down sides.

The improved print files have 3 new components:

1. Additional holes for 3 status LEDs in the control box
2. One combined module for the back plate, the heater base and the mos fed holder (may need some support to print)
3. A shortened spool holder from Armin3dps project to fit on 230mm print beds an without the silica box

From the two original projects you need all parts except the ones mentioned above.

Hardware:

• 3 additional holes for status LEDs
• combined module for back plate, heater and mos fed holder
• shortened spool holder for 230mm print bed and heated dry box

Software:

• can use either with Arduino Nano or Wemos D1 Mini with sensor date transmission via mqtt
