Summary

A robot hand, printable ready to use. No assembly required! To make this happen, I designed a special joint: no overhangs exceeding 45°

Modeled in Rhino.

Instructions

The idea: Just print out the hand (hand.stl) on an Ultimaker, a MakerBot, a RepRap, or another sufficiently capable 3D printer.

Note: There are gaps between parts as small as 0.5 mm! I suggest first printing a single joint (joint.stl). If the joint does not move, then scale the model up. If it is too loose, then scale the model down.

Let me know if you need something, for example an STL mesh with different density.

Bernhard Kubicek has successfully printed a scaled up joint. See the photo, as well as his blog post: Printing a part of a robotic hand…
