Gridfinity 5x4 rugged case

I really like the parametric Gridfinity Storage box by Pred, but I don't need the stackable design. And I even like the look of the rugged box by Whity more. So I combined both of them in a 4x5 Gridfinity box.The box holds 6U high bins and when closed prevents spilling from one bin into another one. It is designed to be sturdy enough but still as slim as possible.Compatible Gridfinity binsThe bin on the pictures is a 1x1 6U high standard bin. You can get it here: https://makerworld.com/en/mo
