Designed this for .1mm layers, you can use my color bender for assistance with the shading.

I included 2 sizes but it can be scaled just be mindful of the Z height. I would keep that at 100% 

Filaments I used

1.  IIIDMAX Black PLA+
2.  Repapper Silk White PLA
3.  Kyuubi Silk Blue Sapphire PLA
4.  CC3D Silk Dark Silver PLA
5.  FlashForge Silk Skin/Peach PLA
6.  Kyuubi Silk Red PLA
7.  Apcvo brown PLA (only brown I had)
8.  FlashForge Silk Skin/Peach PLA
9.  Kyuubi Silk Red PLA

let me know if you have any questions.
