This new version of my Plow Horse http://www.thingiverse.com/thing:40537, is split into two halves that allow printing on most machines without raft and minimal supports. The trade off is that the parts must be glued together. I use a slurry of ABS dissolved in acetone. Slight sanding of the mating surfaces may be useful. I did this modification so that the horse could be printed very small, down to HO gauge scale whereas the original was almost impossible to clean up the supports without breaking the very delicate legs.
