Large 7 port siren

This is a large 7 port siren that, when used on a 3450 RPM motor, will sound like a Federal Signal STL-10. The included bushing is for a motor with a 5/8 inch shaft and 3/16 in. keyway. If you print this, you can modify the file for the bushing to fit whatever motor shaft you need it to.
The rotor itself measures 7.5" by 2". The stator is 8 inches on the outside so you will need a printer capable of printing these dimensions.
