Cardboard Spool NFC Tag Holder & Clip

A simple, snap-on NFC tag holder specifically designed to slide securely onto the rim of cardboard filament spools (like those from Polymaker, Inland, or Hatchbox's cardboard variants). Sized to perfectly and safely accommodate standard 25mm NFC sticker tags, this holder makes trackable filament inventory effortless without damaging the cardboard spool. An easy-to-use, slide-on NFC tag holder for cardboard filament spools. Cardboard spools can vary slightly in thickness, so this clip is designed with a snug, friction-fit tension to hold firmly onto the flange without bending or tearing the cardboard. Just stick your 25mm NFC tag onto the flat circular face, and slide the clip over the outer edge of the spool. It keeps your NFC tag highly visible and easily accessible for scanners or phones while managing your filament via Spoolman or other inventory systems.
