My pal Phil pointed me to a Thingiverse page by Tony "Isotelus" Kramer with dozens of 3-D printable droids and it's pretty impressive. While Hasbro and Lucasfilm focus mostly on the main characters, fan-made creations may be more and more common as these made-on-demand figures look pretty spiffy. If you have a 3-D printer (and I don't) you may wish to give these a try.
