I couln't do any specific work on this one due to a restrictive licence but it prints well.
It should be easy to separate the horns if you want to be able to print it at ful size.
3dmf is what I think is an optimal orientation and setup (worked very well for me).
Printed on an X1C, a textured plate, eSun PLA+ White Bone.
