PSU Cover for Zonestar P802QR2

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:2936831.

This is a remix of dfmsguitar`s excellent Power Supply Cover for the Zonestar P802QR2.

In this remix I have

1. Included more ventilation.
2. Tweaked size slightly to accommodate the smaller version PSU.
3. Included 2 tab returns to the back of the component to retain the PSU more firmly.
