Ok, I got this idea from the recent ramanPi spectrometer project - fl@C@ designed the 3D printable parts for his project in OpenSCAD which allowed him to set parameters that can be changed to automatically alter the geometry of the model. This lets you to easily change parts of the design to tailor them to your own needs. For Stickvise I will definitely do this for the jaw plates, allowing users to set the height and width of the jaw plates to suit a particular project, then just 3D print the customized files. I could also see having a parametric file for a set of v jaws that lets you tweak the depth and angle of the v.
