This might seem strangly specific, but I was looking for a storage box for my iFixit Moray set that met very specific guidlines. 

1:  It must be able to be stored in a Gridfinity bin

2:  It must be able to be stored in the open or closed position, without the lid required to be seperate. 

3: It must have space for extra 4mm bits from other random kits.  

4: It must be able to have other gridfinity bins stacked ontop of it.

Because I couldn't find a modle that meet what I was looking for, I made one myself.  It is very rough design, not the best at mesh modeling.  But it has everything I was looking for now.  The lid can be stored under the Moray box when its open.  It also has a few generic cutouts that I use to hold screws when taking items apart.
