A soldier stands in a poppy field at dawn. Lest we forget…

HueForge print profile included, but the basics are 0.08 layer height, 0.16 first layer height. 100% infill.

Four Bambu Lab filaments used (you can sub other filaments but then the results will look slightly different (YMMV):

PLA BambuLab Matte Charcoal Transmission Distance: 0.7
PLA BambuLab Matte Dark Red Transmission Distance: 1.5
PLA BambuLab Basic Yellow Transmission Distance: 6
PLA BambuLab Matte Ivory White Transmission Distance: 3

Swap Instructions:
Start with Charcoal
At layer #9 (0.8mm) swap to Dark Red
At layer #11 (0.96mm) swap to Yellow
At layer #18 (1.52mm) swap to Ivory White for the rest.

I have included the base image used in the HF project file if you want to try other filaments, but you will need a HF licence to edit it.
