Tag My Spool - NFC Filament

KraftPixel Labs

About this app

Tag My Spool lets you read, write, and manage filament spool tags effortlessly -- so your printer always knows what material it's working with.

Buy NFC/RFID tags like the NTAG213 and stick them onto your spools. You can also make your NFC tags reusable by sticking them onto a printed 0.6mm disc, then stick the disc to the spool using something like glue dots.

Whether you're labeling PLA, PETG, or specialty filaments, Tag My Spool keeps your spools organized with precise data tracking and instant tag access.
