Customizable Vise Soft Jaws (fully parametric!)

After playing around with the customizable vise soft jaws [here](https://www.thingiverse.com/thing:1516335) I realized that I wanted a few changes. I also wanted to get a better handle on OpenSCAD and between those two things I decided to write my own parameteric vise jaws.

This allows for custom jaw width, jaw face width, and overall wall width. You can also change the angle of the lines across the face as well as the position and size of the round stock holder. The "grip" lines cover the full face and you can specify odd wall sizes without getting gaps in the model.

There is also an option for just printing one jaw in case your printer doesn't have the space for two. If you do that you might need to fiddle around with the round stock groove to get it to line up. If you put it at 20% the first time you'll want to put it at 80% the next time and so forth. It should be reasonably straightforward.

I've included jaws for my 4.5" vise since everyone seems to publish either 4
