Boeing X-37 Spaceplane

The X-37 was derived from AFRL's Military Spaceplane program, X-40, which was derived from MiST (Mini-Spaceplane Technology program) which was derived from Rockwell's ReFly program. The X-37 is the same size as the X-40B vehicle, which was never built.
Aside from the history, I had decided to print the X-37 and I sent it to a friend but realized I hadn't included the body flap. He asked if I could include an articulating flap. Well, here is an X-37 with my attempt at an articulating body flap. The one I finally got printed actually has the articulating flap.
This version of the model consists of 7 pieces which you can print multiple options together or as all separate pieces and glue them together. My first print included all as a single print with the vehicle horizontal (no articulating flap). A lot of removing support for the wings and some from the bottom. The top of the body showed the filament lines. Printing the body vertically separately makes for a much smoother finish.
