Pi zero w snap case lid with 3 cherry mx switch slots.

Snap case lid with 3 cherry mx switch slots. I was getting tired of rushing to my PC to cancel prints when the first layer went wrong. I had already printed the snap case (https://www.thingiverse.com/thing:1167846), so I designed a lid to house three cherry mx switches that can control OctoPrint. It's very easy to wire up cherry mx switches to a Pi Zero W. Simply solder one pin of each switch to a shared ground wire and then the remaining switch pins go to their own GPIO pin, with no need for diodes at this number of switches. I followed this guide to write a Python script for the buttons. http://tnorbert.com/blog/2016/10/24/simple-stop-start-button-for-octo-octoprint/
