Description

_Dolphin_whistle_D¤ Length 51,5 mm, Height 21,0 mm, Width 19,0 mm, 11 g.PETG , Support on build plate only (support touching buildplate).¤ Double frequencies on the whistle. Approximately 4,1 kHz and 4,4 kHz .A tip is to clear the whistle with a 0.10 mm feeler gauge after printing.Supports: Touching buildplate only / overhang support only (keep the internal air chambers and labium/window clean and free of support material).Dolfin_ver.F = Length 49,0 mm, Height 24,0 mm, Width 18,0 mm, 11 g.If we adjust the theoretical frequencies downward by 7% to compensate for the actual effects of airflow and the print's geometry, we get the following actual frequencies:21 mm: Chamber 1 3.79 kHz19.4 mm: Chamber 2. 4.11 kHzWith this reduction, the whistle comes very close to the original's characteristic two-tone sound (typically around 4.10 kHz and 3.74 kHz). This gives it that sharp, penetrating referee whistle sound for which the Molten Dolfin is known.
