 - Start the print, wait the printer to pause and insert an NFC tag in the compartment. Stick it using the adhesive side so the 3D printer cooling fan does not displace it during the print.
 - Restart the print and let it finish.
 
+You can also instruct your slicer to pause the print for you. Check your slicer preview to see at what height make it pause. If you're printing at 0.2mm resolution, pause at end of layer 30 to insert the tag and end of layer 40 to change the color.

 The folder to be played is selected based on the TAG content, but may contain more than one MP3 file. In that case, the files must be named as integers with **two leading zeros**, from `001.mp3` to `999.mp3`.
