Where are those plans?  Etsy!   One of the big questions we've had as toy fans is "When will 3-D printing supplant manufacturing in China?"  As of now it's still not ready for the kiddies, but someone on Etsy is charging $20 for plans for a 3D Printable Life Sized action figure inspired by vintage R2D2.  This is something Gentle Giant showed off as an official Kenner-inspired Star Wars action figure product, so it's unknown how Team Lucas and the House of Mouse will feel about $20 for plans to roll your own high-end collectible.  I doubt the final product would be as good as the licensed item right now, but these plans could prove invaluable as printing equipment gets better.
