Egg tray for 10 eggs. It measures 232x91x30mm.

I designed it for my sister's fridge.

Walls are 2mm thick, and the base is also 2mm thick. It's solid enough with that thickness.

I printed this with a 0.8mm nozzle with 1mm line width and 0.5mm layer height, so the base is only 4 layers and the “support” is only 2 walls. I printed it at 40mm/s because I didn't push it too hard, but it's an easy print and can print faster if your heater block can sustain the flow.
