My QI charger is larger than the original design. So I had to increase the size of the circular opening to accommodate it.
Because the opening is larger I had to also move it down in the design, this shortened the channel for the usb cable. The USB cord has some issues. I have a couple of different cables that I have tried with the following results. Some connectors like the Monoprice basic cable are to big to even fit through the hole. The Monoprice select series will fit in the hole, but there is not enough clearance for the wire to bend without propping the stand up (see picture). The Monoprice premium series of usb cables will just fit but has a severe bend.
I may have to increase the base height to accommodate the cord.
