4OutputControllerCase_plus

4/9/2019 Updated and printed. Ran it through Netfabb just to clean up any Tinkercad induced issues.

The original design was nice but had a few issues that I wanted to correct:

1. It is now flat across the bottom rather than having a raised section on one end so it will print better.
2. I like rounded edges rather than hard square.
3. Rather than a solid block "step" I added a design element that also should save filament.

This is still a work in progress and I will publish a picture of it printed when I have time to print it.
