Blow-tuned Helmholtz resonator jar

Play a clear note by blowing across the lid

A jar that hums a note when you blow across the hole in its screw lid, like blowing over a bottle. At this size it sounds close to middle C. The note is set by the hole and the jar: a wider hole or a shorter jar plays higher, so you can print a set and tune a little chord.

Prints as shown on its floor, no supports. The threaded lid and its neck piece print separately; adjust Fit in the Lid tab if it binds.

Filament: at most about 166 g of PLA printed solid (roughly $3.33 at $20 per kg); normal infill uses less.

To get the files, open it in the generator and choose File › Download STL (one file per part) or Download 3MF (a 3MF per part, plus a Bambu Studio / Orca Slicer project with every part on its own plate).
