READY FOR SALE!!! I've completed the final adjustments based on the last physical model I received... it works great and is more stable than I anticipated!
Apple didn't make a dock for iPhone 5, but with the standard Lightning cable and this model, you can dock again!
Not only does this dock give you a solid and visually pleasing place to mount your phone, it also ports through the mic and speaker to the front of the dock.
Once you get the dock, you can do some things to dress it up, such as putting something heavy in the internal cavities to weigh the dock down and add some feet to keep it in place. The current design assumes use of feet like these: Silicone Bumpers - Small (8x2mm, 4 pack)
Based on Apple's dimensional drawings for the iPhone 5
