The individual is using a tool, possibly a screwdriver, to adjust or secure something on the base of the object. The base has several circular holes and a rectangular cutout with a metallic cover. The setting seems to be indoors, with natural light coming in from a window in the background. The person's hands are visible as they work meticulously on the device.
A person is seen using a red pencil to mark points on the base of a dark, textured box that is placed on a wooden surface. The box has a metal base with several holes and a small rectangular opening on one side. The person moves the pencil from one side of the box to the other, marking specific spots on the metal base. After marking the points, the person moves their hand away from the box, leaving the marked points visible.
