A mobile charging cradle for the Xperia Z

This is an extension of a previous project, a charging station for the Xperia Z. I decided it would be nice to have hassle-free charging in the car, as well as a base to hold the phone in a favorable position for seeing navigation.

The new design was made to partially enclose the phone (with its protective case) and have two pogo pins to hit the charging contacts on the side, making it virtually effortless to hop in the car and charge the phone without plugging anything in.

Instead of designing the dock with a specific car or mounting system in mind, I placed two holes matched to the diameter of a wire coat hanger. This allows a mount to be created and modified after the fact, and makes it possible to use the dock in another car without printing another one.

Also this time, instead of using a USB breakout board, I hacked the end off a USB cable, made a channel for the cable in the design, and used a knot in the cable as a strain relief.

The quality of the print was much higher due to using a well-tuned Ultimaker instead of the aging Makerbot used for the last print.
