Foonki Mouthpiece Experiment

prusaprinters

<p>As an experiment, I cut the Foonki mouthpiece end off Justin White's Foonki model I believe was originally invented by Linsey Pollak and scaled that down to 63% so the output tube OD is 12mm and ID is 8mm. &nbsp;I also made the mouthpiece tube a little longer. This was just to test if it would make sound and possibly still be able to connect a tube to it afterwards.</p><p>I printed out of eSun PLA+ in a little over an hour and then cut out a section of balloon and loosely stretched it by hand over the end but so that it was smooth and it was shockingly loud. &nbsp;It sounds a bit like a goose. &nbsp;If I stretch the balloon a little tighter (again with no tape, just held by hand for a quick test) the frequency goes up and is still quite loud.</p><p>It definitely works and isn't hard to get a sound out of. &nbsp;Very cool! &nbsp;Thanks for sharing!</p><p>I printed at 0.28 layer height and used support. &nbsp;It was a little bit of a chore to dig the support out of the mouthpiece tube so I would next time print with support touching bedplate only.</p>
