Beawhistle — beaver whistle, loud twin-chamber, one piece, no supports
A beaver standing on its tail with a chewed stick in its teeth that is also a loud pealess whistle: blow into the stick, the sound leaves two slots between its shoulder blades. Two stopped-pipe chambers of unequal length pulse against each other — measured on the printed part at 2205 Hz with a ~70 Hz warble, the Fox-40 architecture. 99 x 26 x 50 mm, one piece, print-in-place, no supports, no hardware.
