It certainly helps that the USB and power pads on the back of the Zero are available and of a good size to accept direct, soldered wire connections. The USB connections on the hub were a little more tricky. The wires were soldered to the surface mount pins of the mini-B connector. But [Frederick] managed to get that done, also.
A nice advantage of this hack is that a couple of soldered jumper wires let the Zero draw power from the hub’s wall-wart, eliminating one cable from those needed to work with the Pi. Using hot glue for strain relief on the wiring is a nice touch. To keep the boards from shorting he put a piece of foam between them and help them together with elastic bands. Simple and easy.
