Wanhao I3 Duplicator Raspberry Pi 2 Case

When adding Octoprint to the Wanhao Duplicator I3, I needed to develop a case for the Raspberry Pi 2 so that it could be mounted to the printer. This case encloses both a Raspberry Pi 2 and two Switch Mode Power Supplies. The two modules serve two purposes—one to power the Raspberry Pi and another to control the LEDs to light up the print bed.
