This minimalistic egg tray holds 15 eggs, and only uses 80g of filament and prints in 1.5 hours.

Dimensions: 244mm x 146mm x 15mm

Stacks eggs tightly, but will still accommodate XL eggs. Because the height is minimal, this is great for using on shelves with a minimal gap.

There is a slight overlap between the brim and the back-right prime line, using the default printer profile. Makerworld won't allow custom machine profiles, but if you want to avoid this overlap, replace the last 10 lines of your “Machine Start G-Code” with these:
