This is my second design where I included several new technologies and principles. I think it is easier to deal with then it was with my previous version. However the design is radical, so I am planning to post soon my 3rd idea, which will be a combination of the first 2.
Some of the features are the same, like the ball with a rolling bearign inside, also the materials would be the same.
IGES files will be on later this day. *The .RAR contains Solidworks 2013 files.
