robotic or prosthetic hand
thingiverse
Robotic hand, inspired by the Mecha hand. The complete hand stl is just for letting you know how it looks. The finger exploded view is just a guide for assembly. By using rubber bands the fingers will extend after releasing them when they were flexed. Maybe you also like http://www.thingiverse.com/thing:2171811 same principle but servo powerd. Almost the same setup, just need some extra parts to be printed Print Settings Printer Brand: Deltaprintr Printer: Deltaprintr Kit Rafts: No Supports: No Resolution: 0.3 Infill: 30% Notes: Thumb part needs to be printed 1x. Finger parts needed to be printed 4x. Mcp parts need to be printed 3x. Post-Printing Added threads for the bolts. Some holes i enlarged them. So the connected part can move freely around the bold. The exploded stl file gives you an idea how the parts needed to be assembled. I used m3 bolts and nuts for the finger parts and M4 bolts to connect the joints of the finger. The hand plate is bolted on with some m5 bolts. The rubber bands are normally used for braces How I Designed This By trial and error.
