We chose to become creative, and experiment by using bicycle mechanical parts (tube and brake Bowden cable to control the thumb as the forearm stump is moving). We made three design iterations before we came with the final product.</p><p><strong>PRINT INSTRUCTIONS:</strong></p><ol><li>All parts except the fingers: Antimicrobial PLA (Copper3D PLACTIVE)</li><li>Fingers and thumb: Antimicrobial FLEX (Copper3D MDFlex)</li></ol><p><strong>MATERIALS:</strong></p><ol><li>Screws</li><li>Tension Spring</li><li>Bolts and Nuts (we use Prusa spare parts)</li><li>Bicycle Brake Bowden cable</li><li>Rod (We used the bicycle seat tube), diameter: 29 mm, length according to the beneficiary.</li></ol><p>&nbsp;</p>
