Egg Shelf

There are already many egg holders/containers, but I'm creating my own anyway for my special purpose: Wife bought a egg container, which is able to hold 18 - 21 eggs; However, we usually buy eggs from Costco which comes in 24/pack. So that leaves 3-6 eggs nowhere to go and it's causing me OCD problems. So I printed my own shelf which can hold 6 eggs and will sit on top of the existing container, using exact amount of free space in my Samsung fridge. Problem solved!
