Speaker Driver - FD51-4

This is a more modular version of the [Speaker Driver - FD51-4PM (Polymaker Edition)](https://www.thingiverse.com/thing:4127201) and [FD51-4OS 50mm Full Range Speaker Driver](https://www.thingiverse.com/thing:4087953). I created a 2 part screw in chassis to make the part holding the magnets removable for ease of testing. Because of this it is easier and faster to print.
