I used a low poly Jigglypuff from thingiverse and loaded it into 123D Make to make this. First I cut up an amazon box and took the average thickness of cardboard to find it's thickness (~0.11 inches). I then entered that with the model in 123D Make and tweaked the dimensions until I felt like it was about right for the amount of cardboard I have. I then laser cut it and glued it together. Pretty easy and fun, although a bit more time consuming than just 3D printing the same model.
