 My idea with zoe, Michael was to make a model of a tree house. The house's was created by Michaelcc, then zoe created the trunk part on the left, and the star chimney was created by me. We tried two methods, one was to put the house on the tree trunk, but then the house would not print successfully, so we chose the real method now. This is the part I did

 First, I built a model of a sofa and unfolded it. The picture below is the process picture. Then I printed it out on my printer and cropped it. This is a paper model of the sofa I made.

 On the basis of the original, I added several new parts of the expansion diagram to make the model look more solid. Then use Laser Cutter to make the paper cut flatter and easier to fold. Then compare the rendered model to the origami. Here's the final Papercraft! A two-tone sofa and a pillow!
