I found a plan in shop notes on projects to build with a single sheet of plywood. Well, in the shop, I'm cheap, and normally roll with OSB for most of my furnishings, and I really liked their design for a storage cart for cutoff pieces. The design is great for browsing your cutoffs easily and moving around the shop. It is also great for showing how low my supply of long stock actually is since it got all these pieces off the wall.
Well, here it is. Very simple to build, it took about 3 to 4 hours. Nothing fancy, all butt joints, no glue, sitting on casters.
And yes, I'm aware the sides are somewhat crooked. It's a shop fixture, I don't really care. It was a minor measurement mistake with the circular saw so i ended up "pulling" the top of the side in to mate with the middle divider LOL.
