Abstract
An interlocking plastic display has a first member formed as a first shot of an injection molding process. The first member includes a submerged grid system which is formed only where necessary to connect otherwise unconnected portions of the top layer or to stabilize the top layer where openings may be relatively large. An array of spacers is formed beneath those portions of the top layer having material therein, to space the top layer from the bottom of the mold used during a second shot of injection molding. No spacers are formed beneath completely spaces of the top layer in which no material is disposed. The arrangement of the spacers provides an open area underneath the top layer, so that the second member may be formed in the second shot and allows the second shot material to flow around the spacers on the bottom of the mold to interlock the two members.
