This is a Magnetic Charging Dock for Sony Xperia Phones.
The Dock consists of two pices.
1. The Main Body 2. The Slider You will have to buy the usb to magnetic charging cable if you want to charge your phone through this dock.
You will have to print both these pieces. After inserting the Magnetic Charger in the Slider, slide it in to the main body. the rails in the slider should guide itself for perfect fit.
It worked perfectly well for me. Hope it is a useful product for many.
