Large Amazon Echo sphere wall mount

I purchased a pair of the higher fidelity Amazon echo devices and wanted to wall mount them so I would have more desk space. These are the LARGE echo sphere devices and sound quite good. You can tell if this will work on yours by turning them over and checking for a ¼" 20 pitch threaded hole in the bottom to mount them. It's the same bolt used for camera tripods. ACE has these bolts but make sure to NOT bottom out the bolt in the threaded insert since it is limited depth. Mine used 1" long bolts, with a washer. I modified the design to make the bottom thicker, and recess the bolt head so you can't see it. This will mean you will probably need a socket to tighten the bolt. Don't over-tighten it.Actually, snug it finger tight and use the echo device itself to turn it so the cables are in the back. There is a slot in the back for cables to go through and down.
