A 3D model of the 'Hand of the King' pin I made copying the design on the Game of Thrones TV show. Polygonal modelling and sculpting done in Blender.
Wear with caution. The previous two Hands did not live long aftrer their appointment.
EDIT: The new file (Hand_of_the_King_v4.stl) has been fixed and lo longer has intersecting meshes, so it can be sliced in any software with no problems.
The "Hand_of_the_King_v4.stl" should be already scaled and oriented properly. If you have trouble getting the pin to stick to the printbed, try printing "Hand_of_the_King_v4_support.stl". It has a little support that makes it stick better to the printbed and can be trimmed off afterwards.
