About this 3D model

We had a little "3D Printed Ornament Day" at my Deezmaker shop in Pasadena, CA ( http://deezmaker.com ) right before christmas and these are the some of the ornaments I created (except for the angel which is from: http://www.thingiverse.com/thing:34928) Since we are also a hackerspace and SciFi fans, we used some familiar science movie and video game themes: Space Invaders, Star Wars and Star Trek
