This was designed in TinkerCad. My previous 8 port siren was not too good to use. It was set for a weird motor, it wasn't fully round, etc. So I decided to make a new version.
This version is a lot better and is designed for 2 motor types. 280 Micro DC motors, and 775 DC motors. This adds some variety for what people have on hand, or prefer.
The author marked this model as their own original creation.
