Cage Corner Bracket Reinforced

The brackets from atomotec were a little too big for my cage, and when I scaled them down to 85% so they fit one of them broke because it wasn't strong enough.
I loaded the bracket into Tinkercad and added 2 mm to the top and sides and replaced the one that broke.

About a week later one other corner bracket has broken and been replaced. The other four seem ok so far.

I also wanted a bracket for the straight sections so I clipped off the end of the corner bracket in Tinkercad and made it longer for a straight bracket. It ended up being too short to hold well so I am printing more at 150% length.

The straight bracket is uploaded with the original and reinforced dimensions.

Update: The straight brackets tend to split when printed flat on the back, I would try printing them vertically as they are in the stl.
