Double Shepherd's whistle

I've created a variation of the Shepherd's whistle found here: http://www.thingiverse.com/thing:360499, where the tone and pitch play out with greater depth but falter to hit the high notes of the original. Using Slic3r settings might not be ideal, yet they're worth noting: Layer height was set at .3mm, perimeters came in at 5 times, infill settled at .3mm thick. The fill pattern was an octagram spiral design running slowly. Additionally, I chose to combine infill every three turns. Instructions on using the Shepherd's whistle: Start by placing the back of your tongue flat against the surface. Then gently blow into the device. With careful aim, direct the airflow through the top hole where your tongue keeps pressure strong. As you focus the air through this point, a clear bubble begins to form underneath, while inside it grows more compressed. Next comes a force so precise that pushing outward the opposite direction results from trapped pressures so keen. You will observe a clear tone released into air and this noise whistles as well through dividing channels formed with ease between top portions cut slitted deep and those sections beneath that shape the foundation solid - in effect this musical pitch remains consistent even altered greatly based purely personal sound changes, loud quieter blowing tones. Note that an impressive Shepherd whistle video featuring artistic expression: https://www.youtube.com/watch?v=Mv66viUCn1Y demonstrates just what skill levels may reach in utilizing whistles with various blowing dynamics at a talented performer's level
