Printing a whistle

[jcosmo 5]

Hiya,

 

Does anyone have a reliable whistle model, and an accompanying slicing configuration for a UMO?

 

The 'v2 whistle' from thingiverse was one of the first things I ever printed on my UMO, and it worked wonderfully - printed reliably and produced lots of noise.

 

Over the years I've improved/tinkered with my printer, and these days use Cura rather than skeinforge, and now the same thing prints even more beautifully than before, and makes no sound whatsoever.

 

I've tried quite a variety of different settings, even going back to find an old gcode file that I think was an early slicing I used, and the best I can produce is a whistle that sometimes makes some noise, but rarely loudly.

 

Whistles, containing an enclosed ball, are a great print, because of the apparent simplicity of the product, but the impossible nature of the ball, and they work! Or they should.

 

Any leads on a reliable whistle would be great.

 

Cheers,

J.
