Matthew's beautiful Modern Gridfinity case, hacked to fit 5U bins. All i have is the base - everything else you can grab from his model. Not knowing much OnShape, i had to butcher it in Fusion 360. Matthew, i'm sorry! :-).

In order to not have supports, i had to add some continuation of the gridfinity grid. This means there are two very thin slits of Gridfinity - you may want to add a brim if your adhesion isn't spot-on:

For the complete look you can use the 5U Bins and Labels that i've published here:
