Dual Tone Siren - STL files and dimentioned plans

I designed a 3D printable dual tone siren than can quickly and easily be mounted on almost any table grinder!
 
The design is based off a WW2 carter air raid siren.
 
Rotor specs:
Size: d180 x 89 mm
Weight (support structures included) : approx 596g
 
Stator specs:
Size: d196 x 123 mm
Weight (support structures included): approx 568g
 
This Zip folder contains the following files:
- the STL model of the rotor
- the STL model of the stator
- a PDF file containing 7 dimetioned drawings
- 3D printing tips
 
WARNING: This siren is extremly loud. Wear ear protection whilst operatng the siren.
