This is my attempt of creating hair. It did not turn out as good i was hoping for, but i learned alot :D
It needs much work with trimming the hair. Some places the the hair are too long.
Have uploaded a head with bigger horns. Have not tried to print it yet
Some of the walls are a bit too thick
Use a blowdryer to move some of the hair away before gluing it
Then glue it together
Then use the blowdryer to shape the hair
And then it should look something like this...or better ;)
