Having had more and more “stuff” build up on any flat surface or cubby hole. I am trying to at least separate the top from the middle from the bottom. or even get all the parts cut for a project together and not mixed up with other projects. 
I have a pullout keyboard tray that was just collecting junk (I am using a laptop). and stuff was getting lost in the back, so I made some cardboard trays that could pull out like a drawer, and everything in the tray would come out without reaching to find what was in back.
I built it so the sides folded up and it took some pressure to sit correctly while the wood glue dried. After it dried I discovered that being under compression made it stronger.
So like everyone these days, there is an endless supply of boxes about, and the big ones get cut up to be Glowforge fodder, and the smaller ones for shipping stuff out, with 8x10 inches a common size, So I made a bunch of shelves, and more trays to slide in, and in spite of being cardboard with the wood glue keeping joints tight, and not having everything perfect is stronger than if it was perfect the way truncated triangles are stronger than perfect rectangles.
