Here's a crude sketch but it would not let me make it those dimensions. Essentially this would be a part that lets you screw 6 hard drives to it and then it would screw into the case, or maybe slide into a rail from the front. Still experimenting at this point.

I'm working on designing a 2U case and I'm trying to make some HDD slots and using the U bracket to do it, but it seems there are rather specific size constraints on brackets, so it's not letting me make it the size that I need for a hard drive to slide in it. Is there an alternate way of doing some...
