Worrying noise

I have printed a couple of these for the grandkids and on both occasions have been alarmed by a new rubbing/whistling noise from my printer as it reaches the stage as shown in the attached picture. This has resulted in me pausing the prints and checking for the sound source (belt tensions and more). I have just realised this is due to the part cooling duct on my Mk4s - you know when you blow across the top of an open bottle?

Flashforge finder -> Flashforge Creator Pro -> Prusa MK3S -> Prusa MK4S ->???

RE: Worrying noise

It reminds me of an empty bottle that you blow into from above at the neck.

Don't worry. You've just experienced physics.

RE: Worrying noise

What would really be cool is printing different volume bottles with the same height. Then have the printer play a tune.
