WWII air raid siren

Relive the classic sound of World War II air raid sirens with this exclusive 3D print model.
Designed to actually work, the siren uses 2212 brushless motors with ESCs, controlled by Arduino, allowing speed adjustments, sound effects, and even integration with audio and lighting systems.

✔ Authentic vintage “air raid” style design
✔ Files optimized for 3D printing in FDM/Resin
✔ Functional system with brushless motors (not included)
✔ Electronic control via Arduino (customizable)
✔ Perfect for DIY projects, cosplay, collectors, and special effects

⚠ Note: rotors must be printed in PLA, the rest can be any material you prefer! Fill the siren base with plaster for best results. A special version is included in the files with 2 servos so you can better modulate the sound! Have fun!

This project was inspired by an old Yamaha musical-siren project, so let your imagination run wild and try modulating something in it. The tools are there: an ESC for precise control of rotation, and flaps to open and close the airflow using 9g micro servos.
