The design concept features a thin-walled H-shaped beam, reducing its weight by 65% compared to the previous model (296g, volume 3.78e-5m^3, density 7833 kg/m^3 without bearings). This lightweight design passes FEA calculations for strength under three load cases, with maximum von Mises stresses of 867 MPa, 845 MPa, and 922 MPa, all below the 1000 MPa limit. The additive manufacturing process prints the part perpendicular to its maximum principal stress, as indicated in the provided image.
