I'm fitting out a new shop and trying to build good organization in from the ground up. Wood storage is one of the key items and because I'm a glutton for punishment I decided to try designing a mobile storage cart tailored to my situation. Before I drop $200 and many hours of build time I thought I'd throw the design up here for feedback.
My design goals were to provide mobile racking for 3-5 full sheets of 3/4 plywood and a limited amount of 8' boards, plus offcuts, while keeping the footprint to a minimum. This would be adequate to support one large project (for me) or two smaller ones plus leftovers, which feels like the right amount for me. I am a part-time DIYer so I don't have a need to inventory a lot of material.
I chose a 3x5' footprint as this seemed like a good compromise of size, capacity, and stability for handling 8' lengths and full sheets. This fits completely onto 3 4x8 sheets. Probably my biggest question is whether 3' is a little too narrow for stability, particularly if I had 3+ sheets of plywood on it since the load would be biased a bit off center. I *think* so, but this is why I'm asking
Assembly would be a combination of dominoes/screws and I *think* I've thought the sequence through so there are no impossible joints. The fussiest piece will likely be routing the cutouts in the upright frames so that they align well. These are sized so they could fit 6 or 8 inch boards. I added full-length shelves so that these could hold different lengths and make the alignment of the cutouts less critical. There is a little material left over that could be used to make more bin dividers or shelves. My thinking was that the rear could have one side for storing shorter lengths while the other has hangers for clamps and such.

This is modeled in Fusion since the majority of my work has been more mechanical design than woodworking. Happy to share the model once it is finished.
Thanks in advance!
