I take it there's another holder on the other side.
May I ask why the complex shape, rather than just having a triangle with two points on the 4040 rail and the third point being the axle position?
I imagine the "optimized" there means it has the maximum weight support with the minimum amount of filament.
This shape certainly beats a triangle with only the walls or with just a bit of infill. And it surely takes less filament than one with near to 100% of infill.
Nature loves triangles.
