it's recomended print thumb f2 with layer resolution of 0.1mm Post-printting: 1. Sew velcro to the extremes of the palm piece (you may put them over an elastic band for tighter closure). Also stick an non slip surface in the inner face of the palm.2. Heat the palm and shape it with the hand (you may use a heat gun or hot water, be careful to not burn the person)3. Add silicone on the tip of the Thumb f1 part. (it’s recommended a soft silicone, like the one used for sealing in the bathroom). For shape the silicone you may use the tip of a glove. Cut it from glove, put hand cream in the inner face, fill it with silicone and introduce the 3D printed piece.4. Put the axis (you can printed it or use a metallic bar) between the thumb f1 and the thumb f2 pieces. In the inner add a torsion spring, It will allow that the thumb remain extended. Use the holes in the thumb f1 and f2 parts for hide the coil end. Repeat the same process for the union between thumb f1 and the palm.5. Assemble the index exoskeleton, add a sponge or another soft surface if it’s needed. 6. Pass the wire through the designated path7. Tie the thread at its ends. Add a blind knot for avoiding the previous knot slip.
