Here is my 3 colour Candy Cane Christmas tree,
you will need to print all the parts once, I would advise re-naming the files to the colours you want to help keep track of where you are up to once you have sliced them.
I printed mine in Fillamentum
Pearl Violet, Gold Happens and Everybody's Magenta
and Hawk3Dproto (Polyalchemy)
I hope you enjoy the files and
I printed this one with 10% infill by mistake (Woops), though i think it should print just fine with Zero Infill.
I also used a Brim to help secure the parts to the bed as the footprint is rather small.
