Self-hinged bracelet

I printed this using .16mm layers and the cooling fan on very lightly to avoid the mush with ABS plastic.  No brim or supports.  The design is about 8 inches long and will snap together.  To make a necklace, just print out a couple of these and snap together.  This design self-hinges very easily with the built in clearance, and on a heated bed with abs adheres well.
