Decibel Test Video
This is a duck call me and my students worked on to learn about 3D printing and modeling. It works great. We did have to sand it a little to get it to fit smoothly in the tube. Also the reed should be sanded fairly smooth. Print took 2.5 hours at .2mm medium fill on XYZ printer.
You might have to slightly bend the reed away from the sounding board to get it to make a sound. Also try blowing very lightly at first and adjusting the reeds position.
I've include a slightly thicker reed if you are having issues printing the normal one. The thicker reed requires more air to make a sound but as such can produce a louder sound.
One thing I'd like to do is print the stopper in a flexible material. Sadly our printer will not do that.
If you print one please share. My students would love the feed back!
I'll update soon with a video with the duck sound it makes.
We've decided to submit this to the #MakeItLoud competition on the off chance we win a printer (then we can print with flexible material).
Current call is about 84db according to Sound Meter app on Android (see second video).
Medium or High
I printed mine at .2mm with a medium infill. I printed some with very little infill and the (stopper and sounding board) broke eventually when I taking it apart testing different things.
