A tray for a medical device assembly includes a tray body, a tray lid, and a connector arm. The tray body and the tray lid each have a first surface, a plurality of walls extending from the first surface, and an open end opposite the first surface. The connector arm is coupled to the tray body or the tray lid, and has a first position that permits the separation of the tray body and tray lid, and a second position that couples the tray body to the tray lid.
