Dial face creation tool

This project is an OpenSCAD file which creates dial face artwork suitable for use on embedded electronics projects, or other 3D printed projects. Basic features include: number of major ticks, enabling minor ticks, major tick artwork choices, numerical labels, and settable 'keep-out' angles. All features are settable in the code, and final output can be exported as 2D artwork suitable for use on templates and stencils. Simply set the input parameters, use the 'projection' output option, render the design, and export as 'PDF' and a cut-and-pasteable image is prepared to use in artwork templates for potentiometer control knobs. Especially useful for DIY electronic projects, like guitar pedals or other embedded controllers with potentiometer control inputs. Could not easily find anything on the inter webs, so I wrote this. Enjoy, and feedback welcome!
