Pink insulation foam, a hot glue gun, a heated foam cutter wand and scraps from a Death Star Escape playset. Painted with acrylic paints and then the floor was coated with Modge Podge for a glossy black floor look. The power core is removable and is made from Robotix pieces with the Death Star Prison Cell playset pieces and is open for inserting LEDs in to. I want to add a full LED set up to the door way lights as well as electronic panels, but for now, this is it.
