Pretty Good sounding 3 inch Speaker Box. This is of my own design for my specific speakers that I had laying around from a previous box build made out of wood.

Original Version is the one that is Pictured V2 is just a lower profile version (Shorter Print time)

Easily could be adapted to add some LED's to it.

Also at 100% scale the dimensions for the acrylic side panels are very easy. They are 6x4.25 inch. I had a 6x8.5 inch of acrylic and made the box to fit half of that.

I will also add a model that could be printed for the side panels but I like the acrylic look better.
