A test of my Mark3 hand finger

I'm testing out parts for my Mark3 hand. I'd thought I'd upload the tests here.
Received the parts from shapeways. There are issues with each part, but if I combine the bits that work, I should be able to design a working piece. Also discovered a new tool in my 3d editing program, which allows me to make more complicated (but predictable [going for engineering as well as art!]) pieces.
