Recommended Print Settings This model was prepared using a Bambu Lab P2S with a 0.4 mm nozzle.

We recommend keeping these settings when printing your own customized version, especially if your logo contains small details. How to Install the NFC Chip The optional NFC pocket allows you to embed a 25 mm NFC sticker inside the keychain during printing. NFC pocket dimensions: 25.4 mm diameter × 1 mm depth. Enable the Add NFC option in the generator before downloading your model. Open the generated 3MF file in Bambu Studio. Orient the model with the QR-code side facing down. Slice the model and inspect the internal NFC pocket in the layer preview. Add a print pause immediately before the pocket is closed. For this model, the insertion point is approximately 1.8 mm in height, but verify the correct layer in your slicer. When the printer pauses, carefully place your programmed NFC sticker inside the pocket. Make sure the NFC chip is no thicker than 1 mm and sits completely inside the pocket. Resume printing to seal the NFC chip inside the keychain. Important: Program and test your NFC sticker before inserting it. Make sure the chip is positioned securely and does not protrude into the nozzle's path. If you don't need NFC functionality, simply disable Add NFC in the generator and print the keychain without the internal pocket.
