Top Shelf with no Gridholes for Gridfinity Storage Box Shelves (Parametric)

I have copied the top cover and created a version that is completely free of Gridfinity cut-outs. This means the whole thing can also be used as a shelf top, and you can still place small items on top of the boxes. The latch has also been shortened so that it does not protrude beyond the edge. Please take care not to confuse these with the standard ones, as the short versions are very difficult to release again because they have no edge to grip.
