This is a charging dock for the iPhone, the regular charging cord that comes with the phone should press fit into the charging slot. The phone should be a good slip fit with the dock, and the charger end should be held tight enough that when you undock your phone, the charger remains pressed into the dock. I uploaded the Autodesk Inventor .IPT file if you'd like to edit it. If you want one for the iPhone 5, let me know.I used PLA 40mm/s feed 100mm/s rapid .27mm layer thickness
