Air Raid Siren - Kurbel1 with GetrAdapt

I joined Kurbel1 and GetrAdapt, so it will withstand more mechanical stress. At a smaller scale GetrAdapt was the part that broke every time due to tensile force of the thread. I had to print it 3 times until I decided to join it together with Kurbel1. Now it's rock-solid.
