I made this project inspired by the movie BIG HERO, I realized that it could be joined by magnets and I made holes to place it, still in development process and have just printed some pieces but hopefully this project inspire you to improve the model. Some parts I thought it would be best to paste it with some kind of glue such as the face and back covers When in printed model i made at 50% of size. I joined model with magnets, I used 7x3 mm Neodymium Magnets EDIT 19/03 I Repaired Face Center because the model can't be printed. I printed the legs of the robot in low quality without supports.
