I scaled this up by 15% in Cura, and used a 30% infill. I used a brim and would not recommend it because it makes cleaning the fox a hassle. Also, I'd advise against using a raft as well. You do need to use supports. ~60 grams of filament used.
I converted an image of a fox found here: https://s-media-cache-ak0.pinimg.com/564x/f4/38/c8/f438c8bd3915a4b9f73da4b5f66f7852.jpg into an stl. I also used the knots from this project: http://www.appropedia.org/File:Dcee4777vk2015.jpg.
