I thought I would show this off, these are my main skills. I am a prop builder, I have built tons of these, along with other props, which includes Star Wars, Back to the Future, Star Trek, and I am in the process of working on some TF related ones as well. So as you can see it's made from MDF and Styrene. Once I get to the detailing phase it will then consist of MDF, styrene, resin, and metal. A lot of time goes into making these, as well as a fair bit of money. I'm only at about 1/4% completion on this, I still have the Lower Module and Proton Gun to build, as well as detailing it and adding the lights. Hope you guys enjoy.
