I kept having some trouble with the wireless QI charger for my Nexus 7, so I decided to build a base that would house both in the perfect spot for the best wireless connection. I've uploaded the sketchup file so anyone can modify the original design to fit their own wireless charger and Nexus 7 2013 case. I printed this in red abs with 20% infill. I had to use rectilinear infill and finish modes, as the typical archimedean chords I typically use kept crashing Slic3r on this specific design. I would recommend cutting out some of the base to save some ABS, and also widening the walls around the Nexus 7. The 4mm walls really didn't do so well and split when I printed them. I'd recommend widening them more to 7mm or 10mm if you can spare the plastic. The overhang of the tablet at the top of the base was by design. My Printing area can only handle 200mm on the X and y axis. I am using the Poetic Revolution case for Nexus 7 FHD 2013 model. http://www.amazon.com/Poetic-REVOLUTION-Android-Manufacturer-Warranty/dp/B00E7FY8P2 The wireless QI charger I have is this one: http://www.amazon.com/Wireless-Charging-Plate-Smart-phones/dp/B00HJ2KEMQ/ref=sr_1_14?s=electronics&ie=UTF8&qid=1424476030&sr=1-14&keywords=wireless+qi+charger
