Pi 4 2U Rack-mount modular shelf piece

thingiverse

So I built this nicely constructed rackmount Raspberry Pi setup, but then I needed a second row for my switch. That's why I wanted just a basic shelf. This is my first remix and I'm hoping not to catch flak for it because I didn't do much to modify this design. I simply took an existing bracket and cut it down to size so the bottom of it would fit properly. The nice thing about the original designer was that they made them interlocking, so they fit together nicely. To make it work in my specific application, I had to use a spacer at the end. Right now, I'm using zip ties to connect the U's as I have them stacked and not actually connected to a rackmount. I should have tried adding them at the top too, then adding the threaded bolt for extra strength. That's something I might do in the future - I just don't think I have enough extra threaded bolts.
