This is a dock I designed for the Samsung Galaxy S4 with "Crystal Skin TPU Silicone Case". It has the following unique features: -A separately printable slot plate, which can be used to attach the dock to "Dream Wireless Universal Car Mount Holder" - A $6 item on Amazon. -The ability to hold the phone in either landscape or vertical orientation. -A cavity in which the power plug can be (optionally) glued, making it a "drop-in" powered dock. Print the dock in the "connector-cavity down" position. I suggest using a 3mm brim so it will stay put later on. I think I used 2 vertical shells for added strength, but I'm not sure it made any difference. It is fairly strong anyway. The slot plate can be hot glued directly to the back of the dock, or make and attach your own custom adapter. To make it a powered dock, fish a micro-usb power cable up through the hole and plug it into the phone. Tack it in place, then remove the phone and fill the cavity up with glue.
