About this 3D model

I followed this, https://www.google.com/search?client=safari&rls=en&q=how+to+convert+123D+creature+to+.stl&ie=UTF-8&oe=UTF-8 , using this model, http://www.thingiverse.com/thing:258658/#instructions . I didn't know whether it mattered to make the file AscII or Binary so I just ran them both through the whole process. I exported the models as .stl from Netfabb (not the ascII option). It is supposed to be ready for MakerWare but I have not tried it yet. Tomorrow! M
