This drying box is designed with a dual-compartment structure to ensure safety and efficiency.

• 🔥 Heating Compartment: One section houses the heating elements and a fan. The fan circulates hot air into the main chamber, creating a controlled environment that effectively dries filament spools.
• ⚡ Electronics Compartment: The second section contains all the electronic components, including the Arduino controller, wiring, and safety circuits. This separation protects the electronics from heat exposure.
• 📟 User Interface: An LCD display provides real-time information, while indicator LEDs show the humidity status inside the drying chamber, allowing users to monitor the drying process at a glance.
• 📦 Modular Design: This box is specifically designed to be anchored to another box, which serves as the storage unit for the filament spools to be dried.

👉 Note: This file only contains the main functional systems of the project (electronics, heating, and airflow). The storage box for filament is a separate structure to which this unit can be attached.
