About this 3D model

Please also check out my latest design, a Long Range Dog Whistle at 7000 Hz . Please download here . I have also developed real Ultrasonic dog whistles at 20,000 Hz and above, which you can find here . WARNING: This is a dog whistle and not a toy! It's very loud which can harm the ears, so please protect your ears and don't use it near other people or animals! This dog whistle produces a very loud tone of about 19 kHz . You'll probably think that the whistle isn't working - but that's because humans (especially as they get older) hear higher tones less loudly or not at all - unlike many animals! I therefore recommend a frequency measurement app for testing. I use this android app . How to print: Use a line width of 0.4 mm and a layer height of 0.2 mm, 6 top layers and 6 bottom layers. The whistle requires correct positioning of the Z-seam - it shouldn't be placed in the narrow air passages inside the whistle.
