NeoPixel Jewel mount and case for Anycubic i3 Mega S spool holder

thingiverse

This is a simple holder and case (though one could also call it faceplate) for the Adafruit NeoPixel Jewel (https://www.adafruit.com/product/2226). The mount is designed to go onto the spool holder of the Anycubic i3 Mega S. Since that's also where I put a Raspberry Pi camera (see https://www.thingiverse.com/thing:4705413) I designed two mounting options: * one for a single ball mounted accessory * another one for two ball mounted accessories Depending on your print's accuracy mounting the Jewel module on the face plate might require some slight sanding-down of the two pins. I've connected the NeoPixel Jewel to the GPIO ports of a Raspberry Pi 3B running OctoPrint and am controlling it via the great Enclosure plug-in (https://plugins.octoprint.org/plugins/enclosure/). During printing the LEDs are white to provide better illumination for monitoring the print via the RPi camera. Other than that I'm using different colours to show different system states (print finished, print paused, printer ready, etc.). Oh, and if you're wondering what the last photo is: Those are all the prints it took to come up with a working solution.
