Its all made of styrene. I cut the piece and layered them, cut some grooves into the plastic for the door seams. I used light weight sheets for the "light panels" and just cut the rectangular shapes with an exacto. I then mounted them on thicker sheets with holes slightly smaller than the panels to allow light to pass through. Once in place I primered the surface and applied some spray paint. I am also doing the semi circle light panels as well.
