Giant Hidden Shelf Edge Clock

This is make of [DIY_Machines'](https://www.thingiverse.com/DIY_Machines) [Giant Hidden Shelf Edge Clock](https://www.thingiverse.com/thing:4207524). Most of it is stock but I did make some changes. I added engravings to the sleeves so I could quickly tell them apart post-printing. I also had to split the face from the sleeve so I could take advantage of Cura's multi-color support for my CR-X Pro. You may also want to get longer spools of hookup wire as I ran out of red while using only the recommended product. Most of my changes are in the main processor segment. I replaced the Nano with a Nano 33 IOT so I could use NTP over its Wi-Fi. Since the IOT 33 is a 3.3 V device I had to add a [level shifter](https://smile.amazon.com/gp/product/B00XW2L39K) according to [SAMJBRO's post](https://forum.arduino.cc/t/nano-33-iot-and-ws2812b/633556/7) in the Arduino forums. Since I had the breadboard out, I removed the terminal block strips and used the breadboard for power distribution. I think the overall affect really cleans up the wiring in the main processor segment.
