I wanted to give some of these docks as gifts during Christmas to some of my friends. However, not everyone has the same phone.. So while modeling this Iron Throne Dock I kept this in mind. When I constructed this dock I kept the opening big enough to fit my phone and other phones with or without cases. I made the bottom part interchangeable so that way I could make custom pieces that would accommodate different phones. So far I've made attachments for the iPhone 5, iPhone 4/4s, and Galaxy Samsung S3 (or any microUSB charger). I'm currently in the process of making some more adaptive trays for other people who would like to get one of these.
