This is a rendition of a Warhammer Tech Priest's Axehead. You'll need to resize it to your liking and don't forget to add supports, will print better at a 45 degree angle with a tree support structure.

To finish it you will need to bore a hole through the top and bottom axe jaws and place a pole/staff in to complete the prop.

For ultra easy printing, simply sink the model halfway through the floor and print the half that is left, mirror the model and print again, no supports should be needed if you do it this way.
