Stackable & single shelf brackets 7" Topology optimized

I did a remix on NiklasSchoettmer's brackets as i wanted the ability to stack them but also scaled them upto 7" too (although you can scale them to whatever you want)

There are now 2 files, the first one has no cut out reliefs so can be used as a single bracket or at the start of a stack, the second has the cut out relief so they can be stacked.
