🔧 How to Use

1. Design your 3D printed gadget with a 26mm+ cavity for the tag
2. Print the enclosure, peel the tag backing, and stick it inside
3. Use any free NFC writer app (NFC Tools on iOS/Android) to program the tag
4. Seal the enclosure - done! Tap with any phone to trigger the action

📐 Design Tip

When designing your 3D printed enclosure, leave a cavity at least 26mm wide × 1mm deep for the tag. Keep at least 0.4mm of wall thickness between the tag and the surface - thin enough for reliable NFC reads, thick enough to protect the tag. Avoid placing metal directly over the tag as it blocks the signal.
