This here is me and my wife's progress on Julius Perdana's Papercraft Optimus Prime. We've been working on it for around two months. All that's left is the arms. This has been an amazing model to work on. what you see is 213 pages of 110 lb cardstock. 39 make up the arms, for a total of 252. It's not exactly practical in the sense that it's huge(it took around 5 color ink cartridges to print out the parts, for example.), and it has some inaccuracies(wheels, some details on the legs) but all the parts are simple and are designed pretty well. I've only had to modify a few parts to get them to fit properly. The joints, most notably in the arms, hands, hips, and feet are all designed to be moveable. However, I'd recommend putting some sort of stuffing or reinforcement in the hip sockets. my prime is all wobbly and needs to be glued in place upon completion because I overlooked that. Aside from that, he's covered with some spray protectant for sealing ink. He makes a wonderful display piece, given you have the room. He's well over three feet tall. As you can see, he's bigger than a wal-mart three tier bookcase. You can see scout class brimstone hanging out on a shelf for a size comparison If you want to give him a try, all his parts can be found for free at paper-replika at the following link: Transformers hope you like what you see! thanks for looking!
