iPhone 4 case That really fits your phone. It's not really the case with all the iPhone case models.   I printed lot of prototypes in order to find good margins. normally, as long as you print this in a standard rigid plastic, You can take your phone by the case and shake it without any problem. Solidworks Source files are available. Feel free to make your own ;)Printed fine in PLA with 200µm precision. You don't need any support.
