Stacking aid for canned food

We need a stacking aid for ‘un-stackable’ cans. Most of the cans in Germany are stackable but some not. This is my solution to solve this problem for cans with the dimensions: 55x38mm. The full height is 204mm. I've added my design file if you need other dimensions.

But be aware if you put cans inside which are stackable you can't pull them out. 

As always: due to my fusion licence you are not allowed to use the file(s) for commercial purpose.
