Quick and dirty 5 minutes craft: Draw a rough shape, define the contact surfaces & load, click run, and get the optimized shape. The last step is converting the output to a printable shape and running one more simulation to double-check it is strong enough.

This particular holder is a filament spool holder designed to be loaded with up to 5.5kg of filament (1x2.5kg, 3x1kg).

    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.

        I don’t follow you. Look at the photo, the thing is made of triangles. It’s the best shape. So I wonder, why use more than just one? Why make the shape require more than one triangle?

          Hum, ok, I misunderstood you.

          Your 1 triangle will need the inclination similar to that middle segment of the bottom side of the piece. I will be huge.
