This was printed without any support material at 60mm/sec print speed
0.5mm nozzle and 0.3mm layer
Chopped in half and scaled with Netfabb and Sliced with SF41.
He is 1.5 X bigger than the original as a weedy dino is not as much fun.
When printing the Bottom half the back fins will sag as they are not supported, he looks ok, so give it a try.
