upgraded AIR RAID SIREN - 3D Printed

I made air Raid Siren (which I called version 1) earlier. but it quite didn’t sound like the real air raid siren. The real ones have Dual tones unlike mine, which had single tone. So I want back to fusion and designed a new version which I have shown in this version. This Siren sound so much better, Real and louder than the version 1. Enjoy. I’ve included few links where you can purchase the parts.
