Silent Anet A8 Electronics Case Cover OctoPrint Raspberry Pi Zero W 4 Channel Relay Enclosure

This case cover accepts a 4 channel relay board that I'm controlling using a Raspberry Pi Zero W running octoprint. The original case was meant for the larger Pi2 but 2 of the holes line up perfectly for Pi Zero W and leave some extra room for cables and connectors. You need a few custom circuits to drive the relay module, Pi IO ports are 3.3V, the relay board needs 5. This was very easy and inexpensive to accomplish

The purpose of the relays is to use octoprint event functionality to turn on
