A workbench (worktable) model, with shell's and lights casting the dust particles on the table. (books what you see in the rendered picture are NOT included) I used this to render a basement but you can place this anywhere you like. The walls and windows I used are included for free. (with the wall paper textures)
Also the Light, magnifying-glass, item box with screws, table mat, coffee cup and stains on the table are included for free.
