Print & Calibration Notes: Because of the microscopic internal geometry, these whistles require perfectly calibrated filament for precise accuracy. I achieved optimal results using manually calibrated SUNLU High Speed PLA+ 2.0, printed with a 0.4mm nozzle, 0.4mm line width, and a 0.1mm layer height.
