"A fussy and worry-prone protocol droid, C-3PO was cobbled together from discarded scrap and salvage by a nine-year old prodigy on the desert planet Tatooine. Young Anakin Skywalker had intended the homemade droid to help his mother, Shmi. With limited resources, the droid that Anakin built was truly remarkable. It lacked an outer shell, though, and Threepio had to live with the indignity of being 'naked,' with his parts and wiring showing." - www.starwars.com
