ESP32C3 Mini Expansion Module Enclosure

1. Structural Design

The enclosure features a screw‑fastened top-and-bottom cover design, with pre‑drilled openings for the Type‑C port and observation windows for the pins, ensuring precise compatibility with the ESP32C3 mini mainboard and expansion baseboard. Mounting holes are strategically placed around the perimeter to facilitate secure attachment to robots or experimental platforms, offering a well‑organized layout that balances protection and cable management.

2. Printing and Assembly Process

The model is optimized specifically for 3D printing, with the housing and cover designed as a single unit that can be easily separated, minimizing the need for supports during printing. Inside the enclosure, precision‑molded locating grooves accurately hold the circuit board in place, preventing movement and simplifying assembly—ordinary self‑tapping screws suffice for quick installation, making it compatible with mainstream FDM printers.

3. Functions and Application Scenarios

This enclosure provides dust‑proof and accidental‑contact protection for the development board, while its transparent window allows convenient external connection of DuPont wires for debugging. It is ideal for IoT experiments, smart‑car projects, and sensor‑data‑acquisition applications, serving as a practical accessory for ESP32C3‑based maker projects and enabling easy physical encapsulation of devices.
