Stepper Motor Air Raid Siren

thingiverse

This is a siren printable on medium sized printers. It's about 250mm across at the wide section of the horns but those can be split into 2 prints if needed. It's setup for a stepper but whatever fits will work! Design is based on some old siren I seen on youtube. They never said the name of it. It's 240mm wide at the widest point and 150mm tall assembled. Use M3 self tapping screws to assemble or drill and use nuts. There's no real way to hold the rotor on to the shaft, it's a tight friction fit and I plan on using some super glue on it. #Thank you!
