This is a picture of the lid. The lid is constructed fom hardboard 5mm thick with the topside having a melamine finish to it. The lid has a hole cut in it for the fine mesh to go under. The mesh is glued onto the underside with silicon cealer. The mesh provides the ventalation needed. The wire you see coming out from the top left of the lid is for the incandesant light fixture, which holds a 15W blue tinted bulb. All this can be purchased from you local DIY store.
