Mini Cassette Tape Keychain with NFC Tag

This design is inspired by the classic compact cassette tapes, perfect for retro music lovers and vintage technology enthusiasts. But it’s not just a decorative keychain: it incorporates an NFC tag, allowing you to program it with links, contact information, access credentials, or any other functionality compatible with NFC technology.

3D Printing Instructions

• Suggested material: PLA or PETG

Embedding the NFC Tag During Printing

To properly integrate the NFC tag into the keychain during printing, follow these steps:

1. Pause at layer 245: Configure your slicer to stop printing at this layer. This will allow you to manually insert the NFC tag.
2. Resume printing: Once the tag is placed and secured, continue printing to seal it inside the keychain.

• Approximate dimensions: 50 mm x 30 mm x 3 mm
• Slot for standard NFC tag (25 mm diameter)

Note : The pause for embedding the NFC tag is set at layer 245, assuming a layer height of 0.12 mm.

If you change the layer height in your slicer settings, you will need to recalculate at which layer to pause. 

Make sure to check your slicer preview to confirm the correct pause point!
