蝙蝠俠徽章雙色

I stumbled upon a cool batman logo from bio827 and immediatly wanted it printed dual color. I sliced original model into base plate meant to be printed in yellow and separate batman symbol and outer oval ring to be printed upon the fit model using black filament.
I prepared gcode with cura, had to tinker with standard settings for second part. What I did was:
unheck "Automaticaly drop models to the build plate" in preferences
using move in Z direction raise model to the right height - which was the thickness of the fit part, in my case 1mm
uncheck "Remove empty fit laye" in mesh fixes section
that being done, as soon as the fit yellow part was printed i switched filament to black and printed top part right on the base one. I think it looks cool.
