Remixed: Reduced the mesh to be small enough for tinkercad. Titled by 5deg so I could split it in half for better PLA printing with the reed fully on one side. Made the reed a bit thicker because it did not print with my 0.4mm nozzle. Maybe it does not vibrate anymore? It still makes a scary sound, but I don’t know if that is how it is supposed to sound. After printing the halves separately, I first glued together the inner chamber and then glued on the back.
Doesn't sound too good, but holding it sideways and mostly covering the lower hole sounds best. See and hear the finished build here: https://youtu.be/tho2PT0T7w4
