The file 'Nexus 7 (2013) Laser Cut QI Charging Alignment Frame' is (svg) file type, size is 2.5KB.
I bought an inductive QI charger which is designed for cell phones, but also charges my Nexus 7 tablet. The only problem is that the tablet needs to be precisely centered to be charged, which takes a bit of effort to get exactly right, and if it's bumped off center it stops charging. So I built this frame that sits over the top of the charger and holds my tablet exactly centered over the charging coil.
It's made up of 3 layers of laser cut plywood, one around the charger, and two identical ones to frame the tablet. I stained it with an "Ebony" color after gluing the layers together.
The specific QI charger I have is this one: https://www.amazon.com/s/ref=as_li_ss_tl?fst=p90x:1&rh=n:2335752011,k:qi+charging+pad&page=2&keywords=qi+charging+pad&ie=UTF8&qid=1514427429&linkCode=sl2&tag=burningorg-20&linkId=f27c1fa122d959d6062e5f66ec6fb661 but if you have a differently shaped one you can just edit the center cutout of the charger base file.
