An example support structure assembly is described as including a brace, a media guide, and a compression member. An example brace includes a structure defining a mount area on a first surface of the brace and a first protrusion extending from a second surface of the brace. An example media guide includes a blade member, a hinge member, and a second protrusion extending away from the hinge member. An example compression member is coupled to the first protrusion of the brace and the second protrusion of the media guide to place a force on the media guide where a vector defines the force with a first component magnitude in a first direction towards the mount area that is greater than a second component magnitude in a second direction away from the mount area.
