SUNLU RFID Holder (2nd Gen Spool)

I modified an existing model of RFID chip holders to be compatible with NTAG215 RFID tags. This allows SUNLU filament spools (2nd Gen) to be recognized and used with the Anycubic ACE Pro printer, which typically requires a specific RFID format for automatic material detection. The holder was redesigned to ensure a secure fit for the NTAG215 chips while maintaining ease of installation on standard spool hubs. With this setup, users can benefit from the convenience of automatic filament recognition even when using SUNLU. Software used for writing the tags: DnG-Crafts/ACE-RFID: Anycubic ACE RFID Programming This open-source tool (developed by DnG-Crafts, not by me, all credits to him) makes it easy to write the correct data to the NTAG215 chips, enabling compatibility with the ACE Pro system.
