Another Ikea Alex Inlay System

I know there are many designs out there but none fit my requirements, therefore I made a more or less variable version which is based on a third of the drawer depth and devided by four.
I plan to add higher and lower cases to the system in the future. The clips are really simple and small and therefore easy to change and remove teh ox when needed to get something out


I only created a cutout on the biggest box to save plastic, but it reduces the functionality of the box by quite a bit in my opinion.
