This is a high resolution scan of an antler off of a deer. It's about 12" wide by 17" tall but it can be scaled to fit your printer. I tried to set the scan in a good position to print, but some adjustment will be necessary. A great trick is to drop the model into the bed in Z when slicing about 6mm or so. The slicer will ignore what is below the bed and cut the model flat where it drops below the bed, providing a good flat bottom layer.
The scan was done with a David scanner (now owned by HP) with stereo cameras and a turntable.
Edit: Added a lower resolution scan
