Give your iPhone a 1-up! I designed this for my fiance, who wanted a fun charger for work. I based the design from a candy tin she bought at a shoe store (of all places) that was approximately 75% the size required.
See the full-size of the exploded view picture to get the full assembly. It needs to be printed in parts to avoid any problems with printing. Put it all together with 3 3X15 and 3 3X30 dowel pins and a touch of glue. The iPhone connector I'm using is one of the newer, shorter types.
