This is a custom 3D printed enclosure designed for the M5Stack Cardputer, built to house an SD card expansion board with support for CC1101 and nRF24L01 modules. The enclosure acts as a modular addon, keeping the Cardputer unmodified while providing a clean and compact way to attach external RF hardware.

The case is printed in PLA and uses 8 embedded magnets to securely hold the front facing lid in place, allowing easy access to the internals for testing, rewiring, or future upgrades. Inside, there is room for an SD breakout, protoboard, and wiring needed to interface RF modules directly through the Cardputer’s SD slot.

This project is still a work in progress and the design may evolve to improve fitment, durability, and module compatibility. It’s intended for experimentation, prototyping and hacking use rather than a finalized consumer enclosure.
