Don't Panic Nuclear Button

**Update: 2020-02-17** Added files for multi-material printers. Sometimes you just need a day when going all out is the only way to go. I'm diving into Fusion 360, and this project was a blast from start to finish. I printed this using two colors of filament by editing the gcode that Slic3r produced. With 0.2mm resolution, I made the first color change between 35mm and 35.2mm. The second color change happened between 45mm and 45.2mm. In Slic3r, you can turn on verbose gcode output to make it easier to find the layer transitions. The code for filament changes is M600. Just add M600 in between the right layers and print away.
