The prompt
Create a 3D-printable prosthetic hand palm with these dimensions in mm. Main body: rectangular block 85 wide x 100 long x 30 thick with 6 mm rounded edges. On the back (dorsal) side, cut a rectangular pocket 24 x 13 x 30 deep for an MG90S micro servo, and make 5 such pockets side by side with 3 mm walls between them. On the front (finger) edge, add 5 round holes of 2.2 mm diameter for 2 mm hinge pins and 5 matching slots for finger bases, spaced 16 mm apart. Add 1.2 mm diameter tendon channels running from each servo pocket to the finger-base slots. Add a cylindrical wrist connection at the bottom: outer diameter 60, inner diameter 50, length 25, with 4 M3 screw holes evenly spaced.
