SLS printed finger with elastic hinges.

My design for an SLS (Laser sintered nylon) printed hand is moving along slowly.

To the 3D scan of Hollies hand I've added the most promising elastic hinges to the finger. I've also bent back the joints by 20 degrees each. This means that the finger should naturally relax back to a natural straight position, after being bent the first time.

I've now received the finger from shapeways so uploaed some images.
