i cut the cardboard and glued it together to make the main structure of the house. i assembled a 3d printed stairs on tinkercad and 3d printed it. some struggles i faced were when the stairs we made were very weak and couldent hold together. so we solved this problem by gluing each stair to each other individually. a strength i had was designing with Nathan, because i have experience due to my drafting class that uses a lot of 3d printing.
