Fed up with having my Xbox and the associated cables on display, I designed these wall mount brackets. This has enabled me to completely hide my Xbox behind my TV and reduce the cables running from the TV to just one - a single power cable.
The brackets have holes to enable the circulation of air through the air vents on the sides of the Xbox.
I intended on having brackets at the top and bottom of the Xbox, using 4 in total. However, once I mounted it was clear that just the two brackets gave enough strength.
There are three brackets, two (left and right) with small stops to prevent the Xbox from sliding too far. The brackets give just enough space to enable the Xbox to be slid out if needed.
