Motivation

I printed the spiral egg holder but as DrGuido mentioned it misses a cap for the tube in the center. And I see another problem, we get a sixpack of eggs every week from the farmer where we used to go grocery shopping, but the spiral egg holder has 3 slides, so how do you know which one holds the oldest eggs?

So I added a dial to the cap that shows the numbers 1, 2 and 3. 1 is the oldest, 2 the 2nd oldest and 3 the 3rd oldest (or newest). So if you empty the slide with the "1" now, all you have to do is to turn the dial so that the "1" moves to the position that the "2" was. With this move the empty slide should see the "3". 

In that way you can be sure to always get the oldest eggs out first. 

Printing instructions

• Print the cap with the hole in a different color than the dial. 

• Filament type doesn't matter

• No supports needed.
