Summary

I designed an adjustable hand that can fit onto a wrist attachment designed for the SPU 3D printing project.

Assembling the hand

            <div><p>After the prints were finished, I used a shortened 1/4 x 3 1/2  screw to connect the Palm Base with the Mid Hand, and a 10-24 x 3 screw to connect the Fingers to the Mid Hand. The plan was to have a shortened 10-24 x 3 screw for the thumb but we switched to a self-tapping screw.</p></div>
