These models can be printed in 2 colors if you insert an M600 Gcode command in the slicer. Layers 1 to 11 are printed with one color, then the filament is changed and layers 12 and 13 are printed in a second color. Ideally, you simply load the file Voroni_Mix_Coating.3mf into PrusaSlicer.
There will probably be a second version in the near future that also uses a second color on the underside. A different procedure or technique for changing the filament will be used for this.
The author marked this model as their own original creation.
