About this 3D model

Please also take a look at my new Sports Fan Whistle - a full-fledged referee whistle with national colors. I have also developed real Ultrasonic dog whistles at 20,000 Hz and above, which you can find here . Description: This tiny whistle (only 4.8mm thick!) is extremely loud for its size and pretty sturdy. And it fits easily on any keychain. I uploaded profiles for dual color and for single color prints. WARNING: This is an emergency whistle and not a toy! It's extremely loud which can harm the ears, so please protect your ears and don't use it near other people or animals! Please also checkout my other whistle designs :
