Although Admiral Ackbar has a variety of badges (if one looks close), this is a set modeled off his image in the Star Wars Costumes book by Brandon Alinger. These are made available for free to use, but not for commercial sale. If I see these pop up on someone's Etsy site, I will pull these down and file a complaint against the seller. The whole idea here is print for yourself (or have printed for yourself by a friend), as a favor to my colleagues in the Rebel Legion Costume Club.

All that said, I will sell these already made, painted, weathered and magnetted in my Etsy shop "Making stuff 4 fun," but only for those who just need someone to do the process for them. Otherwise, print, fill the print lines with epoxy or Bondo spot filler, sand a little, paint a dark battle-ship grey (these are never silver or metallic in the movies), a little bronze for that one bit on the bottom badge, weather with some dabbed on black paint-wash and clear-coat with an acrylic clear coat (I LOVE to use Polycrilic Semi-Gloss for this kind of thing).

Enjoy Ackbar fans!
