This 3D printed enclosure is designed to house an ESP32 development board and a single-channel relay module together in a compact, well-ventilated case. Ideal for IoT, home automation, and hydroponic control projects, the case provides neat cable management and protection while maintaining access to USB, power, and terminal connections.

The design includes:

• Separate sections for the ESP32 and relay for easy wiring.
• Ventilation slots for heat dissipation.
• Snap-fit lid for quick access and assembly.
• Compact footprint to fit in tight spaces.
