Modular ESP32-S3 Case

This project is a modular, 3D-printable enclosure system built around the ESP32-S3 DevKit, designed to grow with your project instead of limiting it. Just add extension modules to your Base Kit and grow the stack.

The base kit provides a clean, compact, and robust housing for an ESP32-S3 development board, while exposing standardized interfaces that allow plug-in expansion modules to be added later. Whether you’re building a smart home device, sensor hub, controller, or rapid prototype, this framework is meant to be reused, remixed, and extended.

Features

• Modular design – add or swap functional modules without redesigning the whole enclosure
• ESP32-S3 compatible – optimized for common DevKit boards
• Clean, professional enclosure suitable for desk, wall, or embedded use
• Easy to print – no supports required, tuned for FDM printers
• Open-source schematics to encourage customization and community contributions (see PDF in documentation)

Printing Notes

• Tested with standard PLA and PETG
• Recommended 0.2 mm layer height
• No supports required
