This is a remake of a really old Nebulon-B frigate i made years ago. this used up nearly all of my parts. hence the random colours. As you can see there is four layers to the thin middle section. the top layer is plates, the second layer is some technic 1x14 brick's connected by technic pins, the third layer is some normal 1x14 bricks and the fourth layer is more plates. you can actually hold it by the middle of the thin part without it breaking. it stayed fairly well on the chair as well. i may have dropped it twice but there it is.
