NFC filament tag reader/writer for QIDI Box AMS.

This model is a small box I created with custom mounts for a PN532 module and a Seeed Studio XIAO ESP32-C3 microprocessor. It also features an internal cable management "spool" to deal with the excess cable length of the 2.5Ghz BLE antenna (if used.) Assembly of the circuit is easy. Just four wires between the two modules and you are on the air. Along with the Arduino IDE script this implements the Nordic UART Service (NUS) over serial bluetooth to control the reading and writing of MIFARE NFC tags that can be used to tag your non-QIDI filaments for automatic recognition by the QIDI Box AMS. I've also written a companion iOS app that is just now being published in the Apple App Store. The NUS is a straightforward command set that can be easily implemented by other devices that can originate a serial BLE connection. Details for construction can be found on the support website: https://ayefon.github.io/QboxNFCTagger/

I have included both the STEP and 3MF models for ease of adapting this box for your own needs.
