Customizable Phone Dock

I needed a phone stand. I wanted a captive charging cable, so I could set my phone on it at night to charge and I could pick up in the morning to unplug.

I looked around, but most designs with a captive charging cable don't seem to account for a case, and many of them are for a specific model of phone rather than being customizable.

I made it fairly customizable. It could be further customized. :)

Invariants (things that won't change by changing the customizer values):
* plug is horizontally centered on the bottom edge of the phone
* slot for the cable always cuts all the way through the base
* thickness of the base is the same as the thickness of the body (part phone rests in)
* base extends so that the top of the body is centered on the base
* phone covering section always has both back and sides (though it can be eliminated altogether with standPhoneCoverHeight=0)
* corners are rounded with a radius equal to the thickness of the body
