This 3D-printable survival whistle is designed to help you get noticed in emergency situations, reaching an impressive 118.7 decibels when blown at full force. The MakeItLoud V29 is a completely original design built for ruggedness, ease of use, and maximum volume.

Key Features

• Dual-chamber design produces two alternating tones that create a shrill, attention-grabbing sound similar to a pea whistle, but without the risk of jamming or freezing in cold weather

• Extremely durable construction that can withstand drops, impacts, and submersion in water while remaining buoyant and functional

• Easy to grip with textured surfaces and a raised lip, making it secure to hold even with gloves or in your mouth while blowing hard

• Lanyard hole for attaching to keychains, zippers, or wearing around your neck

• Print-ready design that requires no supports, assembly, or cleanup—just print and go

How to Use This File

Download the .STL file and open it in your 3D printing software (also called a "slicer," such as Cura, PrusaSlicer, or similar). The file is designed to print in one piece with no supports or rafts needed—simply load it into your slicer, adjust for your printer's settings, and send it to your 3D printer. Once printing is complete, the whistle is ready to use immediately with no assembly or cleanup required. For detailed printing specifications and tips, visit the full information page linked below.

If you don't have access to a 3D printer, many local libraries, makerspaces, and online services offer 3D printing for a small fee.
