Amazon Echo Dot Gen3 Acoustic Amplifier

This is my first 3D print design.
It works to a degree, but due to its size, the difference is minuscule. My goal is to produce a richer low tone with the Echo Dot but yet be aesthetically pleasing.

Any criticism from sound engineers or acoustic enthusiasts is welcome! let me know where I can improve to make this work in a compact form!

If you want my feature-rich inventor file, let me know and I will attach it.
