Model fixing

Upon closer inspection I saw that my 1:5 model was a bit rough around the edges, so I decided to fix it up a little bit, as well as using actual insulation in place of the cotton balls I was using previously. I have both the insulation and MDF wood as well as a slide track and various other things I need to make my model, thus I thought it appropriate to include at least one of these materials in my "mock up" model.
