Filament Dryer Thermostat using DS18B20 Temperature sensor

3D model description

First Special thanks to MirageC a wonderful design.

I Remixed the design of MirageC for my requirement

This project is very helpful for pre-heating our 3D printer filaments.
The main aim to remove the moisture level of the filaments which helps a lot in improving 3D printing.
The hear of the circuit is Arduino where the code is written in Arduino and we used DS18B20 temp sensor and a relay to switch On/OFF the heater.
The code is written for predefined values like temperature for different filaments available in market along with time.
The predefined values for the filaments can be navigate and selected using 3 Buttons.

I designed PCB in Target 3001! the editable files is also attached.
