4 inch bust depicting a viking in a loose painterly style. The default bust is 4" but it can be scaled up or down easily to your liking.
I have not tried printing it without supports but it "should" work without or maybe with some supports in some areas.
Please let me know if you manage to print it without supports as I won't get around to it anytime soon.
10% or whatever you feel is good.
Again, haven't tested it without supports but may be do-able.
