Low frequency air raid siren with 3 ports. generates a tone about 120 hz. ... Ca.28cm

There's a newer version of this design: Air Raid Siren - hand crank version 2   This design is 100% 3D printed.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...

This is a manual air raid siren hand-cranked in 100 percent 3D printable form. Two rotors generate sound from opposite directions. It has yet to be 3D printed, as printing takes considerable time. Every component must be 3D printed twice except for...

I'm developing 3D printed attachments that can be attached to an angle grinder, producing the sound of an air raid siren. The Makita DGA504 battery-operated tool has the ideal RPM of 8500; however, when used with a standard grinder, the RPM is too...

This is a blueprint for producing an audible alarm in the form of an air siren.

There's a newer model of this design:Air Raid Siren - Hand Crank Version 2.   This model is completely 3D printed and functions perfectly but may experience friction problems when rotating quickly. Use it with caution! Do not touch the...

After I printed MlePh's air raid siren (thanks!), I gave the crank a good spin and hit hard friction before even reaching what I'd call 'mid rpm'. Turns out the slop between the crank handle and bearing allowed 'gear1' to move too much, where it...

This is a mid-1950s Chrysler Air Raid Siren, an essential part of YOUR Civil Defense System. These powerful machines used to be ubiquitous across the country during the Cold War Era. I vividly recall the distinctive sound they produced every...

I built the air raid siren version 2 and encountered some issues during assembly, so I made modifications to make the siren more robust. To print this model, you need a slicer that can handle multiple models at once with different infill settings. I...

This is a 60mm impeller air raid siren. It is extremely loud - measuring an ear-shattering 120 dB on my smartphone app's noise meter. In this video, I throttled the motor back to just 30% because I didn't want to attract unwanted attention from the...

I printed the air raid siren version 2 and ran into some problems when I built it, so I made some modifications to make the siren more durable. Slicing with a slicer that can print multiple models at once with different infill settings is pretty much...

An 8/12 port mechanical air raid/tornado siren. Should be printed with 20 percent infill or more. Motor should come with its own nuts. Use these to secure the print to the motor. The shaft nut is used to transfer torque to the rotor, so please...

This is an air raid siren built to go inside a Stuka dive bomber model. The Stuka was a German terror weapon used in WWII. As it dived to drop a bomb, a siren would sound out from the plane to terrify the people they were bombing. This siren is...

The main reason sirens get noticed is to alert people in the vicinity of a crime or urgent situation occurring.\nA 5:6 frequency ratio, known as an untempered minor third, enables this siren to stand out more due to two distinct tones sounding...

A lot of positive response led me to redesign it, incorporating metal bearings to eliminate friction problems that plagued the 100% 3D printed version. It now runs much smoother! To build this, you'll need these metric [mm] bearings: 1 x 47/25/12 -...

To build this, you'll need the following metric [mm] bearings: 1 x 47/25/12 - SKF 6005-2Z 4 x 16/5/5 - SKF 625-2Z I also attempted to design it with 3D printed bearings, but they didn't quite work out as planned. Fortunately, I was able to source...

The siren is powered by a vacuum cleaner, producing an extremely loud sound. I utilized silicone grease to ensure smooth lubrication throughout the device, and the bold metal components are made of M4 materials. No additional support is required for...

There is also a README.txt if you have problems getting the bigger parts printed on your R2. Designing: I use basic AutoCAD to draw my 3D stuff because i use it a lot on my work. It took me about 200 hours to design this siren. ...I added the drawing...

Settings: - Printed at 0.2mm layer thickness without support, except for the front propeller (0.1mm + support) - Printed in full infill only the small gears and the small axis; others were printed with 20% infill - Used PLA, but as mentioned in the...

I've replaced the "09" plus "15" part by only "09" and a metallic rod of 4mm diameter (fits inside the small bearings). Settings: Printed at 0.2mm layer thickness without support, except the front propeller (0.1mm + support). Printed in full infill...

I corrected the mesh of Kurbel1, which had flawed internal geometry leading to poor print quality.

There's a more recent iteration of this blueprint available at: https://cults3d.com/en/users/MlePh\n\nThis design is 100% fully printed in three dimensions. It functions smoothly, yet may experience resistance when spinning rapidly!\n\nExercise...

... GetrAdapt to make it more resistant to mechanical stress. ...At a smaller scale, GetrAdapt kept breaking due to thread tension, so I printed it three times before deciding to merge it seamlessly with Kurbel1, resulting in a rock-solid final product.
