Ocarina FTW

Description
New Version!
The largest overhang on this version is 45 degrees so there should be no need for support material. I followed the instructions from the website 'PrintTo3D' posted so, in theory, it should make some noise. I also increased the diameter from 30mm to 40mm at the widest point, so hopefully the noise that does come out wont be too high pitched.
I included a couple pictures including one just of the sketches I used to create the object.
New pictures show the old version (left) and the new version (right) which got about 65% of the way done and decided to pop off of the build platform after I walked away for approximately 30 seconds. I'm going to change a couple things and will print off a new copy by friday

It has to be done at tolerances better than a tenth of a millimeter. You might get lucky with it. But if you really want to get it right I there's a small new 3-D printer that can go down to a twentieth of a meter. That would do the trick. Question: Would it be possible to take the Compact Double - English Pendant Style Ocarina sold by STL Ocarina and do some sort of X-Ray tomography, slice by slice at those tolerances and recreate that instrument in plastic or some other material that would be shatter-resistant? I'd love to have one (two!) of those. I have the ceramic one, but I mostly use the plastic 'single' octave one because I can concentrate on the music instead of safeguarding it. I realize this question is very 'cross-discipline' but maybe someone knows... [email protected]
Tried the new ocarina. I had to set additional raft margin to 200% to get a good grip at the base.
But still no sound. I think the embouchure is too small, should be wider, like the whistle. Also its' bend is a problem. I can see some material blocking inside it it, but I cannot fix it because even the smalled file I have does not fit the hole.
I think it would be a good idea to start making a new one with a separate whistle part and glue or snap-fit it together with the ocarina body. So first task should be producing a sound out of the whistle part, then add the ocarina body. Good luck!
I'll print one off after I finish work and report back

Skeinforge is not so clever on supports. It uses way too much material for that, so you have a solid block below the embouchure. It also adds some support on the sides for me..
agreed on skeinforge supports, I printed it and the pipe snapped while trying to remove support material. I'll add some supports while i watch the superbowl tonight.
Might make the bottom a little flatter and remove a few holes, no music coming out of this one...... yet
