This is the iPhone (lighting cable) version of what will eventually be a modular phone charging stand. The two small pieces are a cable adapter assemble sized to fit around an official lightning cable from Apple which then fit snugly in the top channel on the base. The charging cable can be routed out in 1 of 4 directions and the base plate is used to hide other exits. Having multiple pieces also gives you the option for different color schemes.
There are two types of charge adaptors. The open version exposes a bit more of the charging tip by having it flush to a little above the surface of the charge adaptors. Should allow it to work with thinner cases. The other version just has the flat tab sticking up and there is a thin wall of plastic housing the rest of the charge tip for a more finished lood.
If you want to have one made for you just head over and check it out on etsy.
