6 Hole Flute

It works! http://youtu.be/S-z3_xKU77Y
While working with Cymon (who doesn't have a MakerBot) and NYCDESIGNER to try and get Cymon's Recorder design to work http://www.thingiverse.com/thing:11796 I decided I needed a little more SCIENCE! So I wrote a parametric OpenSCAD script based on the Whistle/Flute from http://www.ggwhistles.com/howto/ that allows you to experiment with different hole placement, size, window and lip angles, etc. This flute is much simpler then a recorder (and not nearly as pretty as Cymon's) but it is able to play 6 notes quite clearly and loudly. Now if only I knew how to play the flute...
This is still a work in progress because I think I can get the mouthpiece/lip to print a little easier. It's kind of fiddly to get it just right.

Print bottom, middle, and top and then glue them together. Make sure it's air tight. Then slide on the mouthpiece. You may need to carefully file the lip to make it nice and sharp and flat.
Alternatively, you can print top1 and glue it to middle and bottom. Then you have a body and can experiment with top2 and mouthpiece options. Use the joint_ring to temporarily join top1 and top2 together while you experiment.
Don't print assembly_solid unless you have a giant printer with support. :)
