-A small twist on the classic pear of anguish. You can can twist the screw and it will open gradually, or you can pull the handle for the same effect, and lock it in place. It works great with weights too, the heavier the weight the more it opens.-The parts were designed for easy printing while ensuring maximum strength. The flat screw it a perfect example, easy to print laying down, while losing none of the functionality.-For optimal printing results, I recommend keeping the current part orientation.-Use it at your own risk.
