I scaled this up & sliced it in half for easy printing in NetFabb
Place it on the Bed, FLAT SIDE DOWN, add supports under the leg parts and ear.
At 100% it should be around 100mm Long
Suggestion: In your Slicer, Switch Off, Uniform Scaling & Raise Z (ONLY) by 1mm, it will be a bit chubbier, but the horn will be stronger...
Feedback would be great....
