A gray 3D-printed prototype of a car steering wheel, complete with intricate lattice support structures, is centrally displayed on a wooden desk. The steering wheel features a textured grip with perforations and a central hub containing a rectangular recess and two side control clusters. In the blurred background, multiple individuals are seated at wooden desks, observed from behind, consistent with a classroom or lecture hall setting. A partial human finger is visible at the bottom right, near the base of the 3D model. The precise location within Burgas, Bulgaria, is not discernible from the provided visual information.
