SteemPi Case (Steem Insignia Edition)

Customized case for the [**SteemPi**](https://steemit.com/steemdev/@techtek/steempi-v1-0-is-here) project.

Modified from the Pi 3 VESA case from 01110-M-P, though removing the very VESA connectors that game it the name and completely remodeling the top and bottom venting.
