Pittsburgh Penguins

This is very large and you will need a 300mm bed unless you scale down. If scaling, only adjust X and Y. Z layer colors are done by height and you can edit your gcode to use the Filament Change Command (Marlin=M600) at intervals .8 and 1.6mm. Yellow (0mm-0.8mm), White (0.8mm-1.6mm) and Black (1.6mm-2.4mm).
