>>10029973I understand the joints you had your designer create, but they all still offer hardly any useful movement. You don't even need to print it to test out the movement. Just by looking at it, it's clear the arms (red) will not be able to be rotated forward or back due to the shape of the shoulder opening in the torso part (black). The oval shape of the upper arm where it meets the torso doesn't have nearly enough clearance to be rotated forward or back without clashing with the black shoulder socket openings.
And the leg articulation below the waist is all completely useless with V-cut hips. The feet will only ever be able to sit flat on the ground in the neutral standing pose the figure is shown in right now.
