charging dock / cradle

Hi,

Has anyone been able to find a suitable charging dock / cradle for the XRN2?

Case for magnetic dock?

I have been using magnetic dock in my car with original nexus 5 and don't want to give this up. I'm afraid that sticking the magnetic plate inside a regular case will eventually destroy the back cover of the phone that is resting against the plate. Does anyone know of any case with built in metal plate for attaching to a magnetic dock or a two piece case that I can slide the magnetic plate between?
