Mosquito in amber
I printed this with the bottom two layers (0.20mm and 0.15mm respectively) in transparent orange and the top two (0.15mm each) in silver. The model prints with the back facing up and looks best when displayed backwards so the dark mosquito blocks light but can't be seen directly. I used Prusa color change to indicate when to swap filament, but this would be easy enough to do manually. I printed this quite large because I wanted the thin legs to have enough girth to be easily visible, and I'm not sure how much smaller it could go.
