This is an STL of the different colors of Georgia Tech's mascot, Buzz. I just grabbed it from online and converted the picture to dxfs which I then converted to models. This is really designed to be printed multimaterial but you can print the black file standalone and it still looks very nice. You can also add the files together before you print or let me know.
While it can be scaled, be careful about the antenna because they are very narrow even now at full size. I will be experimenting with adding a border in the future to see how that works
Honestly these are very easy prints. Just make sure to level your bed well and have enough top and bottom solid layers so that you get a nice surface.
