Stuka Siren for sewing machine motor

thingiverse

Had my neighbors from 5 miles away complaining about how loud it was. A copy of a Stuka siren, also known as a Jericho Trumpet. Used on German planes during the Blitz as a psychological weapon.to incite fear Use a universal motor commonly found on sewing machines for the drive, can be found online for about 15 bucks with a speed controller. The controller can be used to change the sound and volume of the siren Scale the parts up by 10 and rotate them so the bottom of it is on the print bed. For the chassis, the side with the holes for the motor should be on the bottom, and the blades should have the circular part without the blades on the bottom. Should be able to print without supports..
