Systems and devices using t-slot profiles and clamping devices to form a structure that may position an object in three-dimensional space. The clamping devices clamp two t-slot profiles together, either parallel or perpendicular to each other. The clamping device may be unlocked allowing t-slot profiles to move relative to each other, and then re-clamped, to lock the t-slot profiles in a new position. In some embodiments, the t-slot profiles and clamping devices form a structure that may position a camera in three-dimensional space over a table that supports at least one item to be photographed, and optionally digitized. The photographed items may comprise blueprints, artwork, architectural plans, and more.
