noob

Hello, long time lurker but first time poster... Finally made an account today. When I first saw the S4 I immediately fell in love. It's such a pleasing case to look at, and the amount of power you can cram into it is absurd. I've been doing a bit of searching and this is what I've come up with...

Hey guys, i'm working on a personal project to make 2 different styled cube cases that i have the dimensions on in my notebook and i'm wondering if there is a way to use pre made models and just import the dimensions of said components? If so, how? Thanks, Mike.
