We're all waiting for someone to sell that fancy orb docking station for the Nexus 4. In the meantime, Ingenuity never rests and this 3D printed dock would make an awesome substitute. It uses a standard USB cable for charging, and an NFC sticker to trigger the NFC Task Launcher app to drop it into dock mode.
If you have access to a 3D printer, be sure to give this one a good look. And if you make any extra ones, give me a yell so I can throw my money at you.
