Start with Black At layer #5 (0.32mm) swap to Gray At layer #18 (0.84mm) swap to White for the rest. Print at 100% infill with a layer height of 0.04mm with a base layer of 0.16mm
I like the idea of it, but the numbers are all wrong. I opened it in Bambu Studio and it shows only 12 Layers not the more than 18 that you say. Finished product is .60mm thick. How many layers total should it be? It also appears to be missing Silver as well. Otherwise the picture is just okay.
