Duplo Millenium Falcon playset for the kids. It's open on the top for easy access.
About this creation
I made this for my kids a few years back. Luckily the shape of the Millenium Falcon is so recognizable, because the color scheme started falling apart. I followed the published interior of the Falcon pretty closely, not that the kids cared about that. They were probably more impressed with the size -- 3 ft x 4.75 ft (1 meter x 1.5 meters).
Here is a shot with the "exterior hatches" open. I say that very loosely, but they do swing open and closed...
I neglected to get a shot with the smuggling hatches opened up, but I circled in orange where they are.
I was able to use some of the translucent Duplos to good effect on the rear. I like how it turned out.
Here is a close up of the cock-pit, complete with ... is that Han?
I didn't realize how large this was until you flattened out a child next to it. XD Either that or the young man is 20 inches tall. (Kinda doubt that.) Understand the color issues given the size. Looks like an absolute blast for any kid, it is rather an iconic shape. Love the Han Duplo in the cockpit. Impressive, most impressive.
