This is the 12 hole Ocarina designed by nimaid, calibrated by RobSoundtrack and cleaned up by TheRapidPro. Very easy to remove supports. Just print and start playing. Main profile is set to 25% infill which is sufficient for a playable ocarina. I've found that 100% infill just feels nicer in the hand.
Here is RobSoundtrack's demo of actual playing:

Note: Main picture is one I printed with the seam set to “Aligned” instead of “Back”. The uploaded profile is correct and will not put seams on the front face.
