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... ivanogre@gmail.com

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!

does the new one work?

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

I know little to nothing about musical instruments, but if you get one working I'll print one out on my Dimension SST 1200es.

I thought about printing one, but was skeptical about it working.

I think the no music part has to do with the embouchure. It's too big and it's round. It should be more like a small slot, like a flute.

so awesome! I'm printing this right now. Now I just gotta figure out what special prize to send you. :)

Award everyone, and ship out Batch 11! :-D
