***Edit: I have the kinks worked out, the ball and socket system works great now***

I have been hard at work on what I think is a killer accessory for Stickvise, a 3d printable gooseneck helping hand arm. The design is not 100% ready for public consumption, more in beta test phase. Currently the ball and socket fit together flawlessly, but the locking nut on each joint is a bit difficult to turn. This is the piece that prevents the joint from pulling apart. The fit is something I should be able to sort out in the next week, just need some time to iterate the design a few times. In initial testing, this gooseneck has over 5 lbs pullout strength, so it will not come apart unexpectedly. Feel free to try printing it out, STL files are available on the gooseneck project page:
