Baking Tray Stacker with Storage Stand

I have seen a few different designs of clips that allow you to stack baking trays/sheets on top of each other when cooling. However, they only seem to work when the edge of the trays/sheets are thin meaning that they have something to clip onto. Our trays have wider and flatter lips around the outside so the clips don't work. I designed this so it will work with a variety of trays and even different sizes (just put the largest one on the bottom). It is closer to shelving than clips. For easier storage, I designed a simple stand that holds them together.
