This is a stand for 7" display. You need 4 M4 nuts, 4 M4 screws with length of 14 mm and 6 M4 screws with length of 10 mm. Also if you want to use it as wall mount you need screws to screw to wall. This is my first project I used Autodesk Fusion to design.

It can be used horizontally or vertically.
