How to prepare parts for mixed colors printing?
I ve been searching a lot about mixed colors printing.
I am about to buy a diamond hotend, and I read carefully this article. http://reprap.org/wiki/Repetier_Color_Mixing
I just wonder how to color the parts to be extruded, like to obtain a result like Kharar got on that part: http://www.thingiverse.com/make:194938
