ADVANCE FOR MONDAY APRIL 3 AND THEREAFTER - In a Tuesday, March 21, 2017 photo, Liza Naydanova ties wire on a 3-D-printed prosthetic hand as Jordan Smith holds it steady at All Saints Episcopal School in Tyler, Texas. The students are part of a group making a prosthetic arm and hand in partnership with the Center for Affordable Prosthetics that will eventually be used by Osman, a 22-year-old man who lives in Honduras.
