Gridfinity storage box - alternative easier to open latches

I found opening the latches for the great gridfinity storage box https://www.printables.com/model/543553-gridfinity-storage-box-by-pred-now-parametric quite a struggle with my big sausage fingers, plus when two boxes stacked - the latch on the lower would butt-up to the one above (see 3rd picture) requiring opening of top box latches to split the boxes. So I created this with a larger finger hole, and a slanting opening to avoid the stacking proble m above.
