I liked the Voronoi deer remix by 3DDEDCLUB, but had some issues printing when scaled down.
I took the original model by yeg3d and made a version with more even edge width across the model. Also made the voronoi pattern cover the bottom of the hooves.
Included is also the laying deer model.
For better results try adjusting xy compensation (horizontal expansion) to obtain an edge width that works well for the chosen scale.
Update 2021: Added some lower poly models.
