Siren

This is a Siren that was designed in Fusion 360. This is a remix of the item 370886. Since I didnt want to use a BLDC motor and associated equipment, I have made this to be able to use with a simple DC motor. I am linking the exact motor I used. The top is fixed to base with m3 screws that are tapped into the top. If you dont have M3 screws lying around you can also glue it instead. model prints in three parts and doesnt require any supports. I also made it smaller than original design so that the dc motor I had could handle it. I also slightly modified the impeller design, I thought it would improve the air flow. it makes pretty decent noise.

the motor I used is :
