Hanging Speaker Shelf

I wanted to hang my large Sony Center Speaker above my TV. I found a shelf bracket or something (I can't remember which one now) and did some duplicating, resizing, adding, etc. This is what I came up with and it works great. I printed two, and have them facing each other. The speaker fits inside. I printed it pretty heavy duty (35% infill & thick walls) so it will be sturdy. It prints with minimal supports if you'll print it on it's side.
