Lack Enclosure Paver Braces

I found these Paver Braces (https://www.thingiverse.com/thing:3240687) but after printing them out I found out they screw into the hollow part of the leg, basically rendering them moot

So I whipped these up in solidworks.

Print with 10 perimeters for strength, paint support enforcers on the 45 degree overhangs of the vertical ribs and the bottoms of the two horizontal ribs in the corners, paint support blockers in the screw holes
