Wireless Charging Stand for 7-8" tablet

Update-January 6 2017: I cannot no longer recommend using the charger/receiver combination below. Mine has either failed (after 11 months) or the IOS 10 update is somehow preventing it from charging now. I am now charging my Ipad the old way with the lightning cable.

Charging stand for 7-8" tablet, using PowerBot charger. Shown is Ipad Mini 2.

Use layflat function in Slic3r to lay the stand on it's back for printing - no support material required.
