This is a tutorial to make a SONG for adding to finish printing, this is one of the things i did to personalize my Da Vinci Jr converted to RAMPS 1.4.
As we know you have to use GCODE M300 to Play beep sound in our printers. Well all we need is to convert a song into an old format used by nokia phones to play songs. RTTL.
All you need is to find the song you want in MIDI format and after that search online a WEBSITE online to convert MIDI to RTTL
There is a lot of more websites where you can do the same thing.
After that, you need another website to convert from RTTL to GCODE.
Just copy the gcode generated and paste into the ENDING SCRIPT GCODE of your printer profile.

NOTE: The STL is just for requeriment of Thingeverse you dont need it.
in the download section is the code used in my printer. You can test any song just by print in your printer. dont worry it will just play the music.
