In this instructable I will show you how to use multiple processes in Simplify3D to print multiple colors with only one extruder.

I prefer this method compared to pausing the print manually and swapping color because I don't end up with a blob of filament where I paused it. I can prime the filament so only the new color comes out the change. Also the extruder could move out of position using the pause method.

I will be using my remixed version of the cover from the Raspberry Pi Zero NPR One Radio project by Adafruit.

If you want to follow along I have posted the files on Thingiverse. http://www.thingiverse.com/thing:1647961
