This is a transport holder / egg crate / carton thing for GOOSE EGGS. These eggs are large, and aren't particularly fragile, but are still difficult to keep safe when transporting in the car. I didn't feel like buying a 100-pack of cardboard egg crates, since we don't sell very many goose eggs. This eggcrate costs about $1.50 and uses 71 grams of filament. Print time is a bit high, but the quality is worth it; for faster print times, use 0.20 mm or 0.25 mm layer height (no other changes are required, the mini can handle the fat extrusion at 30 mm/s). 

I found that 105% tall and 95% in X/Y is the best for our eggs. You can see from the picture that there is a huge variability in egg size. The design is relatively compliant but becomes pretty stiff once it has eggs in it.
