This is an edit of this thing: http://www.thingiverse.com/thing:200824 I´ve cut it to get a flat bottom and rotated it to achieve nice teeth without support. The tongue is now fixed to the mouth at both sides to become printable. There is a simple support for the spikes, but they are still difficult to print. Now you can print this nice dino without extra support and receive a very nice model with lots of details. It´s also a good stresstest for your printer.I´ve printed the dino with 0.1mm layer height and 3 perimeters. The infill is 20% and there is no extra support. With this setting it last nearly 12 hours and needs about 13m of 3mm PLA Filament.
