I needed a way to mount my 19"(10" should work too) Switch to my TV Board. I came up with this solution, just print both pices, clip your racknuts into place, screw it to your device, then mount it with standard screws on your furniture. This way you can mount any 1HE/U device to every furniture, as long its not to heavy. I found out that its also not required to screw the holder into the furniture, but i would recommend it.

How i printed mine:

• Material: PLA (PETG, PLA+ might be better)
• Layer Height: 0.2
• Infill: 50%
• Orientation: Top down
