Woodbending form for iPhone 4 case

In order to make a wooden iPhone case, I printed a plastic form to bend the wood around. See images of the finished case and the full build documentation here: http://cre.ations.net/creation/wooden-iphone-4-case

The form is slightly larger than a real iPhone 4 both because of shrinkage during the print process and wanting to make the case still slightly larger than an iPhone 4.
