This is a modular drawer system with a built in gridfinity grid for organization. I added end stops to each shell to prevent drawers from coming out all the way. This allows you to inspect the contents of your drawers without worrying about the drawer falling out.
I want to thank the creator of the Modular Gridfinity Drawers for sharing the onshape link. This made remixing it a breeze. In a similar fashion, here is the CAD that I modified if you want different sizes or to make more modifications. https://cad.onshape.com/documents/8b56ba3570c716a2ffbd9f8f/w/f6635a553ea7aa29e8d93f4c/e/5cc1941be1c349fb5b529e29
