The file 'T-Rex Necklace Pendant 3D Printer Model' is (stl) file type, size is 12.0MB.
I printed this at .1 mm layer height to get the most detail. It took about two hours to print without support or raft.
I also did this at 80mm/sec print speed and 100mm/sec traverse speed. I would suggest slowing this down a bit more to capture all the detail.
I suggest that you also superglue the bottom half to the upper so it doesn't just pop right out.
