This is an upgrade of the stand from http://www.thingiverse.com/thing:128986. I purchased a bare charging board from dx.com (http://dx.com/p/qi-standard-wireless-charging-transmitter-module-green-269662) and integrated it into this stand. The 2013 version of the Nexus 7 supports the Qi wireless charging standard, and this board from DX is the lowest cost Qi compliant board that I have been able to find. Wireless charging is awesome because I don't have to plug in the charger daily. I made one charge stand for my night stand and one charge stand for my desk at work and now my battery is always full! One issue is that both of the coils were damaged in shipping. You can see in the picture that upper left corner of the gray material behind the charging coil is chipped off. Everything still seems to be working even with the corner chipped. When I notified DX they gave me a refund for the charger boards.
