Smart NFC Keychain - Minimalist & Customizable

Overview: This is a sleek, functional NFC keychain designed to be printed with the chip embedded inside. It is perfect for digital business cards, smart home automation, or quick social media sharing. The design is optimized for a clean look with a clear "signal" icon to indicate the touchpoint.

How to Print (Important - Manual Pause): To ensure the NFC tag is completely hidden and protected, you must insert the chip during the printing process:

• The Pause: Set a Pause Command in your slicer (like Bambu Studio) at the specific layer where the circular cavity is about to be covered.
• The Insertion: When the printer pauses, place your circular NFC tag (25mm diameter) into the slot.
• Resume: Ensure the tag is flat and doesn't interfere with the nozzle, then resume the print to seal it inside.

Software & Customization: To program your keychain, you will need to download an NFC writing app on your smartphone. I recommend using "NFC Tools" (available on the App Store and Google Play). With this app, you can write URLs, contact info, or automation triggers to the chip.
