Fractal Vise concept study

This is another version of the Fractal vise people are working on. Concept 6 is working well enough to share.

The goal was to have a tight a fit as possible and to have as wide a range of motion as possible. Total width is 80mm. Height is 16mm. It's quite possible to scale these up independently in the slicer. But they will not be compatible with vise.
