Print your own easy-to-play instrument in one go with no supports. This wacky instrument is extremely intuitive to play, and has a great sound to boot! Print in low layer heights for faster print times, or smaller layer heights for a smoother finish. Print at 100% concentric infill, or increase the number of walls for best results. The sharp angled part by the mouth is what affects the quality of the sounds, so make sure that it's as sharp as possible before playing (sanding or cutting works best when layer widths are high). Remixes welcome, just let me know that you've done it!

Great as a stocking stuffer!

EDIT: New low note versions added that play lower notes more easily. You can try both and determine which is easier for you to play.

EDIT 2: After printing, check the sharp angled part that goes in front of the mouth. This should be as clean and sharp as possible to get the best sound! If you are not getting any sound, clean stringing or hanging plastic and sharpen it up. You can even sand it to be as sharp as possible. I've included more pictures to show what it should look like.
