Pan flutes in various keys and scales, with a hexagonal aesthetic so can print 'em flat and annoy anyone around you! 🎵
These models come with no guarantee that they'll be usable musical instruments--I just made 'em for fun. Your mileage may vary. You may need to tune the pipes a little, as with any pan flute.
The one shown is pan_flute_a4_minor_1octave.stl, if I remember! After wrapping my head around bore length calculations, I'm not sure if I have a functional mind anymore. It was playable after some practice.
The hexagonal pipes are designed so that you can print these flat (NOT the default orientation of the .stl files!) without needing supports, and that orientation also makes it easy to do simple multi-color variations with as few as one material swap/pause.
Most of the variations will fit on a Bambu Labs X1C build plate or similar. There are also some smaller 1-octave variants that will fit on smaller print beds.
The author marked this model as their own original creation.
