Bring a little high-tech convenience to your everyday carry! This Smart NFC House Keychain combines a sleek, modern house silhouette with functional tech. By embedding a cheap, standard NFC tag inside, you can turn your keychain into a digital multitool.

✨ What can you do with it?

  • 📶 Share your Home Wi-Fi: Let guests tap the keychain to instantly join your network—no more typing long passwords.
  • 🔐 Smart Home Trigger: Tap it when you walk through the door to trigger automation routines (turn on lights, adjust the thermostat, play music).
  • 📱 Digital Business Card / Link Tree: Instantly share your contact info, social media, or portfolio.
  • 📞 "If Found" Emergency Contact: Program it with your phone number or email so an honest finder can reach you instantly.

🛠️ Assembly & Hardware Required

This model is designed to encapsulate a standard 25mm NFC Coin/Sticker (NTAG213 or NTAG215) seamlessly inside the print.

  1. NFC Tag: 1x 25mm Circular NFC Coin/Tag.
  2. Hardware: 1x Standard split key ring.
  3. The "Pause" Method:
    • Slice the model and add a Pause at Height/Layer right before the printer covers the internal NFC cavity.
    • When the printer pauses, drop the NFC tag into the slot.
    • Crucial Step: Ensure the tag sits perfectly flush or slightly below the print line so the nozzle doesn’t strike it when resuming!
    • Resume the print to seal the tag inside forever.
