So I saw this, and saw its reinforced version. Both left a little to be desired, or rather, a lot to be desired, in terms of design. They were blocky, they required a lot of material, and were inefficiently designed. So, at great length, I extracted the important dimensions from the STL in Fusion 360 and redesigned it to be a little more elegant, that is to say, with not much more material, it's now a lot stronger and more rigid.
