Invisible Airport Express / Apple TV Wall Mount (adaptable)

I have some airport express devices to expand my network and I wanted to mount them on the wall. There are several options for this already on Thingiverse (referenced below) but I wanted to have an invisible wall mount. So here's my contribution to the pile of mounting options.

This also works for the Apple TV device (I believe mine is a 3rd Gen version).

Parts and Materials

• Three #4 pan head screws where the head is 2.5mm thick or less.
• 5 minute epoxy
• 3D printed centering ring, glue mask, object plate, wall plate

Process

Attach centering ring to device. Place glue mask inside the centering ring. Apply epoxy. On the underside of the plate that attaches to the device, apply epoxy without going past or filling the ooze channel. Remove glue mask. Use a thin layer to prevent oozing.

Place the object plate that will be attached to the device in the centering ring, open end pointed toward the side with all of the sockets if you want the cord to hang downward. If you are careful about the amount of glue you use, you can leave the centering ring in place. If you fear side ooze, remove the centering ring or it may get glued in place.

If you get side ooze into the center channel you must remove everything, clean off the epoxy with acetone, and start over. If you fill that channel with ooze, it won't slide onto the wall plate. Finally, place a weight on the piece and let it cure (one hour for 5 minute epoxy).

Screw the wall plate to a wall with #4 pan head screws, and slide the device on the wall plate. This sounds sort of involved, but when I videotaped the process, it took just under six minutes, most of which I cut out for the demo video.

0.5 mm Nozzle

My printer (Lulzbot Mini) has a 0.5 mm nozzle installed. If you have a printer with a smaller nozzle, the parts might be a tad loose. You can either scale the wall plate up to account for this in your slicer, or you could edit the source files which I have included (freeCAD native file format). You may also have to scale down the centering tool to remove unwanted play.

Stick on Anything

There is no reason this process couldn't be used on any device or object (of appropriate weight). I have included the centering square without any arms if you would like a simple way to create an invisible mount for some other object. Just make your own arms and stick the centering plate on them.

Other Types of Wall Mounts

The invisible nature of my mount is cool, but what is less cool is the necessity to permanently mar your device by epoxying stuff to it. The following wall mounts require no modifications to your device:
