With the kind permission of Wing-Art, I bring you a simple remix of this beautifully elegant item of kitchenware, now with twice the fun!
Starting with the stackable version, I increased the width of the base to allow room for a second cup / egg, and increased the overall scale (100% > 102%) for a better fit with larger eggs.
I also chose to move the cups away from the edge, removing a potential dirt trap and making it easier to clean.
