I remixed this file to store 6 eggs instead of 5, because my country sells eggs in multiples of 6. The overall dimensions are slightly larger than the original in order to create room for the center egg, but the circle cut outs are the same as the original (40mm diameter).

I tested the print with conventional "large" eggs sold in U.S. grocery stores and the spacing works well. For any larger eggs, I would recommend scaling up by 5-10%.
