A model of the digestive system of the horse in a body cutout fashion, based on an image from Robert Peterson, 2008, found in this UC Davis publication (dated Oct. 2012) HERE.
Printed in PLA with 0.4 nozzle defaults, tree supports at 45 degrees. Came out pretty well first try, though there were some smaller supports more internal that were more difficult to remove. This was printed for a horse conference for people in the equine vet med community, and thought to share for anyone who may be interested.
The author marked this model as their own original creation.
