About this model

There's a newer version of this design: Air Raid Siren - hand crank version 2 This is an old design! Printers and slicers had other tolerances back then. I have many users complaining in the comments. So be aware of that. This design is 100% 3D printed. Works fine but may have friction trouble when rotating fast! Be careful when using it! Dont touch the moving parts while they are rotating!
