This is for printers with multiple toolheads/tool changer and printers that can automatically swap filament. It consists of multiple parts, that can be coloured differently in each layer. Just pick a part of the print( outline, heart etc.) and choose a colour for it.
I attached the single files, that need to be adjusted to fit together or use the .3mf file to get them in an aligned postion alread.
The author marked this model as their own original creation.
