NFC & RFID Filament Tag Reader, Writer & Spool Tracker for 3D Printers.

Tag My Spool lets you read, write, and manage NFC filament spool tags effortlessly — so your 3D printer always knows what material it's working with. Whether you're labeling PLA, PETG, TPU, ABS, or specialty filaments, Tag My Spool keeps your entire filament inventory organized with precise data tracking and instant tag access.

The ultimate NFC spool manager and filament organizer — compatible with Anycubic ACE Pro, TigerTag, OpenSpool, and OpenPrintTag.
