I have designed a wall mount for the Xfinity / Comcast HD cable box to be mount on the wall or even under a shelf. You can use the mounts in any configuration to suit your needs. I personally used the right & left brackets with the top bracket having the slotted screw hole which allows the bracket to slide for added security.
Since you can configure these in any arrangement, I'm sure they will work for other cable boxes or devices.
Dimensions are: 90mm length, 30mm width, 33mm depth, 5mm in thickness, & mounting holes are 4mm.
Printing Tip: In your slicer, as long as you have the brackets on their side with the end caps on the bottom, no supports are required. The top bracket with the slotted screw mount will require support for that slotted area.
