This is a wall or ceiling mount for the Poly Sync 20 speakerphone. It is a snug fitting bracket that will hold the PolySync in place. It took me a few attempts to get it somewhat form-fitting. It is not perfect, but it is pretty close.

There are two versions. One of them has a notch cut out so it will slide over the Poly logo on the top of the phone. I would recommend using two mounts, regardless of which you choose.

I am including both the STL files and the F3D files in case someone wants to take this to the next level.
