Customizable NFC Tag Keychain - Two-Part Assembly

Keep your digital world in your pocket! This minimalist NFC tag keychain is designed for ease of use and maximum reliability. Unlike "print-in-place" designs that require precise timing to pause your printer, this model features a separate lid and body system, ensuring you never ruin a print by misplacing the chip.

Key Features

• Easy Assembly: Simply drop your NFC chip into the lid or base and secure it with a drop of superglue.
• Decorative Lid: Comes with a clean heart motif—perfect for gifts or personalizing your keys.
• Slim Profile: Sleek, rounded edges make it comfortable to carry in your pocket.
• Durable Design: The recessed lid protects the chip from external impact.

Hardware Needed

• NFC Chip: Designed for standard 25mm circular NFC stickers or coins (standard NTAG215 or similar).
• Adhesive: A small amount of CA glue (Superglue) to bond the lid to the body.
• Keychain Ring: Fits most standard split rings.

Recommended Print Settings

• Material: PLA, PETG, or TPU (if you want a soft-touch feel).
• Layer Height: 0.16mm or 0.2mm for a smooth finish.
• Infill: 15-20% (Grid or Gyroid).
• Walls: 3 walls for extra strength around the keychain loop.

Pro Tip: If you want the heart to be a different color like in the photo, use a filament swap at the top layers or use an AMS/Bambu Lab multi-color system!
