After testing and refining 30 prototypes, I'm now happy to share it. <h1>Key Features</h1> I set out to achieve these goals with this design, and I succeeded: <ol> <li>Easy to print without support.</li> <li>Little pressure is needed; almost impossible to breathe through without sound.</li> <li>A distinct and clear sound: no air hissing through when not in use.</li> <li>Durable.</li> <li>Cord hole.</li> <li>Around 120dB, with no loss of sound quality.</li> <li>Quick water draining: just one shake drains it completely.</li> <li>An organic shape that feels great and won't slip out of your mouth.</li> <li>Symmetrical for faster reaction times and ease of use.</li> </ol> I hope you enjoy this creation, and feel free to share your own makes or suggestions!
