I went ahead and bought the NASA printed SLS model from eBay, I could not find a version of it anywhere else. It is more of a paper-doll style punch-out cardstock model with tabs and slots that interlock. Those were kind of tricky on the Orion model, I resorted to putting a little glue on the tabs and in some cases adding my own glue tabs to help reinforce the model. I may do the same with this model.
The SLS model has several pre-punched all-white parts on a white background, so I really can't scan it, unless I punch out the parts first and put it on a darker background. I will give that a try and see if I can get a decent scan to share here, but the PDF might be too large to post. It's a very simplified model, but might be interesting, not sure if it would be suitable for conversion to a model rocket.
