Adding a Fusion 360 file with a USB-C and 3rd encoder hole

[JamesHagerman]

I tried to redo @james-everitt's work on the USB-C and 3rd encoder hole.

My intent is to improve the design in a few ways, and without his original .f3d file, that was somewhat difficult.

I haven't done a test print of this, but the measurements should line up with the original.

Thanks for your work, James. I don't think I am going to accept any pull requests into this repository from now on since I have no way to test them other than 3d printing a new case, and that's not something I'm going to do. I have made a "remixes" folder with a README.md file. What I suggest is that you fork the repository and make all your changes there. Then make a pull request with a link to your repository in the remixes directory. That way I can maintain a list of all the remixes available. Best, Corey

@coreyker Sounds good! Thank you!
