Hi folks, it's been a while since I've been on.
For a little background, I'm a senior in high school. I've been in a program for three years now called Science Research, where students are given the opportunity to conduct original research, culminating in the writing of a research paper, as well as a variety of science fairs. For my project, I've been working on a design study for a single stage to orbit spaceplane (big surprise) that uses three modes of propulsion to get into orbit and back onto the ground. Here's an excerpt of my paper, to give a description of the craft itself:
"The concept of this spaceplane is a hybrid three mode aircraft based on the design of the SR-71 aircraft. The aircraft is already optimized aerodynamically and structurally for high mach flights, and are proven designs. While it’s the basis for the design, the only visual commonality between the spy plane and spaceplane will be the bird’s-eye profile. From the side view of the SR-71, the design of the spaceplane will be different both above and below the chine of the fuselage. Below the chine, the fuselage will be squared, and covered with heat protective tiles. This has three purposes: one, to simplify the process of applying the tiles; two, to create a lifting body effect on the fuselage; and three, to increase the area inside of the fuselage for fuel. The wings will be lowered and thickened slightly, in order to meet the bottom of the fuselage, and provide more area for fuel. Additionally, the lift from the body will allow the wings to be shortened width-wise, creating a slimmer profile for more efficient high-mach flight. On the wings, housed in the nacelles of the Pratt & Whitney J28 engines used on the SR-71 will be pre-cooled turbojet engines, build to take the spacecraft from the ground to mach 6 and 20,000 meters. Halfway down the bottom of the spacecraft will be the intake for the scramjet, which will take the spacecraft from mach 6 to mach 17, and 70,000 meters. The scramjet will exhaust from the bottom rear of the spacecraft, with the engine also covered in protective tiles.
Above the chine, the body of the spacecraft will be radically changed. The cockpit will be removed, along with the rest of the upper body of the Blackbird. In its place will be a large conformal tank, with a fuel and an oxidizer tank within. Between these two tanks will be a small cargo bay, with a 5,000 kg capacity. At the end of the conformal tank will be two Aerojet Rocketdyne AJ10 engines, proven as reliable vacuum engines over the past 60 years. (May be switched to one Merlin 1D vacuum engine)"
I have the technology and math covered- what I need to do now is create a printable 3d model of it, both solid and cutaway. The images of the craft in KSP included are what amount to a rough sketch for me, as I have no skills in actual sketching on paper.

I'd really appreciate it if y'all could help me create models of this craft, as it would both aid my presentations at fairs, and provide a really nice final product for all the work I put into my research over the past three years.
