Here is a helping hand jig that is useful for soldering, gluing, painting and macro photography. It is highly configurable to hold various small objects in many positions.
The helping hand has six configurable, lock in place, arms with interchangeable grippers. It was printed on a Replicator 2.
The gripper donuts can be cast in silicone or Oogoo and were cast using donutmold.stl.
