Logitech (or similar) Computer Speaker Holders

I wanted to get my speakers up off my desk to make more space, so I designed these simple boxes to screw them to the upper portion of my desk. I made them to fit my speakers which are Logitech model Z213 found here on Amazon,

The holders have a printed inside dimension of approximately 79.5mm both ways (width and depth). I designed them at 80 but that's what my printer made them at, and the speakers fit perfectly. There is a cutout in the rear for the speaker wire to exit peacefully. Two holes are added for screwing them down.

If you need the opening larger or smaller, just scale the design up or down. If you'd like just the opening to be larger, I'll be happy to add a new size for you.
