I might need dinosaurs later for my tabletop game, but instead of modeling from scratch, I grabbed these from around the internet and made them miniature ready gaming! The T-Rex is from http://www.thingiverse.com/thing:135530 by sk8nmike. I fixed up the eyes, and sized it for the "huge" size category. The Triceratops is from http://www.thingiverse.com/thing:182327 by YahooJAPAN. I sized him down for the "huge" size category. The Allosaurus is from http://www.123dapp.com/catch/Dion/2556663 by Mat Paris. It was a pretty massive file, so I brought down the face count, fixed up the teeth and eyes, and sized him up for the "large" size category. The Ankylosaurus is from http://www.123dapp.com/123C-3D-Model/Ankylosaurus/656380 by "Autodesk Premium". I sized it down for the "huge" category, and brought down the face count some. The Plesiosaurus was originally an Elasmosaurus model from http://www.123dapp.com/123C-3D-Model/Elasmosaurus/597287 by "Autodesk Premium". I made the head larger, shrunk down the neck, and matched the face to line up with a Pleasiosaurus skull. Then I modeled a stand for it and altered the body to fit in it. Finally the Pteranodon was from http://www.123dapp.com/3dcr-Creature/Pteranodon/1896559 by Riccardo Bragalini. I sized it down for the "medium" size catagory, and made a stand for it after altering the body some. Use supports and try to print them on their backs as much as possible.
