About
Camping can be very fun, but getting lost isn't. That's why many websites say that you should definitely bring a whistle to any camping or other nature trips in case you ever do get lost. However this is easy to forget and finding a nearby store that has whistles is often impossible. So I designed a 3D Printable Emergency Whistle. This two tone whistle, designed using Fusion 360, creates two very loud tones around the 3.5 kHz range. Both tones/sound waves interfere with each other to create a ringing sound. This unique pitch combination ensures that you can be heard from very far away.
Printing
This whistle is designed with 3D printing in mind and the stl is pre-oriented so keep your default settings except for :
Z-Seam: Print as is with regular settings but position the seam AWAY from the wedge using paint on seams (PrusaSlicer and derivatives) or z-seam alignment (Cura). Position is near the mouthpiece (see picture).
Supports : Do not use! They will be impossible to remove.
