I designed a small whistle as a starting point for a playable ocarina. My plan is to make something that sounds decent as a closed vessel, then drill finger holes starting with the lowest notes. If all goes well and I can get it tuned, I'll measure the holes and add them to the model.
Starting with a 2cm cube I added rounded corners with the built in minkowski function and then added "mouthpiece" using a fillet function I found here:https://github.com/clothbot/ClothBotCreations/blob/master/utilities/fillet.scad
Next I hollowed it out and added a fipple using the technique of TLAR (that looks about right) and was a bit surprised that it actually played a note (sort of). Some adjustments may be needed here...
Eventually I'll make it a bit larger, this was just a quick test print. I'm also trying out some different print orientations. I put it 45deg on edge because that first layer is usually pretty ugly and PLA printers seems to handle that much overhand fine without support. I've also included the STL w/o support in case you'd like to do that yourself.
Thanks for looking!

Update: multiple changes to the .scad file. See github for a complete history: https://github.com/bobm123/maker
I rendered a larger one with interior volume of about 65 x 45 x 25 mm and included a couple of .stl with support options I was playing with. According to my chromatic tuner, print plays a slightly flat C#. Next I'll see if I can make it into an ocarina.
