Super Loud EDC Emergency Whistle V3 - ULTRA LOUD

After many more prototypes and tests, it's here: the V3 Emergency Whistle – the most well-thought-out and efficient version of our 3-tone emergency whistle to date.

The V3 is over 60% smaller than the V2, weighs about half as much, and requires up to 58% less filament – while maintaining nearly the same loudness and impressive stability.

The proven airflow design has been retained, but the outer shape has been redesigned: more compact, more balanced, and perfectly suited for a keychain or EDC use.

Thanks to nearly identical wall thicknesses, the construction remains stable and print-friendly – no supports needed, AMS-optimized, and ideal for everyday use.

Here is the comparison between Version 2 and Version 3

Here are the highlights of the V3:

• Over 60% more compact, ideal for on the go
• Up to 40% shorter print time
– AMS: 1 h 6 min instead of 1 h 51 min

 – Single Color: 46 min 55 s instead of 1 h 17 min

• Up to 58% material savings
• Proven 3-tone system, same clear sound
• No supports needed, print-ready
• AMS-friendly & single-color optimized

The V3 Emergency Whistle is the result of many small, meaningful improvements – compact, efficient, and ready for immediate use.

Print it upright with a 0.2 mm layer height – and if you prefer something larger in your hand, you can find the V2 Emergency Whistle here
