The amount of "trouble" highly depends on the kind of tools and skills you have. For some people just going away from workshop to use the computer in office can be more hassle than taking a piece of wood and shaping it directly. It's the same as machinists choosing manual mill for simple one off parts even when CNC mill is available. 3d printing is good for more complicated parts. Some comments suggest cnc router but simple part like that with the right set of woodworking tools could be made in a couple of minutes freehanding it or maybe using paper template glued to a piece of wood. Also maybe the 3d printer was busy printing the other more complex parts which actually benefit from it. Different tools have different advantages for different parts.
