I was just currious to know if there is a site that is dedecated to schematics for CAD, for like things we might want to design ourselves, like iPhone cases for example. Is there a site that gives out schematics for different products that we can design, or gives out the file itself for us to open. Just currious.
Visit the following blog 3-D Parametric Solid Model Drawing. Here you will find many CAD models (that are free to download) as well as there screencast videos created with Autodesk Inventor software.

There's others, but these are my two favorites.
This one isn't a bad source either...
