Print at 100% infill with a layer height of 0.08mm with a base layer of 0.16mm
Swap Instructions:
Start with Black
At layer #2 swap to Blue
At layer #10 swap to Pink
At layer #18 swap to White for the rest.
it did take me a while to slice for some reason but be patient it does slice, reason why no print profile. so you will have to add the colours
