GalileoHand V.1

thingiverse

The mechanical version utilizes body power to activate/control the grasp, all components being low cost and readily available at any hardware store (screws, bolts, elastic thread, etc.), while the rest are 3D printed. We want to maintain as much functionality in the mechanical version due to its low cost and high reliability; that is why we incorporated a thumb rotation module so that the mechanical hand can do three types of grasping, allowing for things like: picking up small objects, writing, carrying a toolbox, reading a newspaper, and even drinking water. The 3D printed GalileoHand prostheses was designed to be adaptable to conventional mechanical prostheses in place of the terminal device. Instructions are available online at http://www.instructables.com/id/Como-construir-la-Galileo-hand/. To construct the device: print all large parts with a thickness of 0.2mm or 0.3mm and a filling rate of 30% or higher; for small parts, like sliderAdjust and the SliderHolder, print at 0.2mm thickness and 100% fill; when printing the fingers, supports are recommended. It is also essential to rotate the proximal finger parts by 35 degrees so they become perpendicular to the surface. Furthermore, print the palm vertically where its bottom rests against the printer's base plate and use support brackets as needed. Instructions for construction can be found at http://www.instructables.com/id/Como-construir-la-Galileo-hand/, and tutorials on its assembly and usage are available online.
