I made this Millennium Falcon Cockpit Diorama out of a cheap styrofoam bait bucket. I cut out the window section first, then I put in the floor and covered the inside with cut out pieces of sticky-back foam sheets to make the surfaces consistant and smooth. I used paper clay to fill in some of the gaps. I carved the dashboard out of that soft green floral styrofoam and glued it into place. I painted the inside with a mixture of gray and silver acrylic paints and plain old elmer's glue. I always try to make these dioramas look like they're made out of plastic, like they're real toys and playsets. I stapled on the headphone wires around the arch. I cut out flexible, soft foam and painted it white for the padding along the inside of the arch.
I made the back wall out of foam core board. I cut out the doorway and used the sticky-back foam for all the raised panels. All the different plastic bits and pieces are just odd-ball parts from models, ear-bud headphones and an old cell phone. I painted and added these pieces to the back wall and the dash before I put on the back wall so I would have more room to work with. Then, I used masking tape to fasten the back wall to the bucket. Finally, I covered the whole outside with cut out pieces of the sticky-back foam and painted it with a mixture of off-white acrylic paint and school glue. I painted some small blemishes on the outside and sprayed the whole thing with dullcoat to help even out some of the paint and protect it.

"That's No Moon."
I know it's not "Movie Accurate", but I added a couple of hooks on the back wall to hang breathing masks and goggles on and a utility / toolbelt from a cheapie generic figure to the side of the arch for when Chewie has to do some maintenance. The windshield piece is the lid from a pringles can and the steering contols are a set of trucks from an HO scale railcar toy.

I wanted the base to look nice without drawing too much attention. I made it out of two pieces of styrofoam packing material. I glued them together and covered them with some of that sitcky-back foam. To finish it off, I covered it with a mixture of black acrylic paint, school glue and craft sand. It kinda looks like it was carved out of stone.

"She'll make point five past lightspeed. She may not look like much, but she's got it where it counts, kid. I've made a lot of special modifications myself."
