This is a remix of "Topology optimized shelf bracket". The original is great, but the design was not what I was looking for in my office. I created this remix before I realized I needed it to be bigger than would fit on my print bed. I did not try printing it. Although, I intended to print on its side with extra perimeters. Feel free to try if you wish. Hope it works. If not, let me know and I'll remove it.
