1. A device, comprising:
a support arm assembly for a head-worn device defining an electrically grounded enclosure for a projector configured to provide radio frequency (RF) shielding for the projector, the support arm assembly comprising:
a metal support arm:
configured to form a rear face, a bottom face, and a top face of the enclosure;
configured to structurally attach to an optical element holder of the head-worn device; and
configured to structurally attach to a rear structural element of the head-worn device;
a metal front face of the enclosure:
configured to structurally attach to the optical element holder; and
defining a front aperture for permitting passage of light from an exit pupil of the projector toward an input optical element of the head-worn device,
such that the metal support arm forms a structural support joining the optical element holder to the rear structural element without placing mechanical load on the projector;
a first side face of the enclosure electrically coupled to the metal support arm; and
a second side face of the enclosure electrically coupled to the metal support arm.
