This stl was created by Hueforge. To obtain good results you have to use the following settings:

Print at 100% infill with a layer height of 0.08mm with a base layer of 0.16mm

Filaments Used:
    PLA BambuLab Basic Black Transmission Distance: 0.6
    PLA BambuLab Basic Red Transmission Distance: 4
    PLA BambuLab Basic Gray Transmission Distance: 2
    PLA BambuLab Basic Jade White Transmission Distance: 5

Swap Instructions:
    Start with Black
    At layer #6 (0.56mm) swap to Red
    At layer #11 (0.96mm) swap to Gray
    At layer #12 (1.04mm) swap to Jade White for the rest.

If you have a filament from another brand you can still get good results in my experience, for example I tried with WINKLE filaments and it is still very nice.
