About this 3D model

A library to generate a printable [auger](http://en.wikipedia.org/wiki/Auger) in one piece without required support material. The STLs provided are not intended for direct use, but instead show examples of what can be done with the parametric script. -Customize the radii, height, number of turns, and even do multiple-start augers. -Vary the thickness to change the tooth strength. -Modify the overhang angle to what your printer is capable of. -Choose a left- or right-handed screw -Library actually respects $fs, $fa and $fn Optionally, add a perimeter of support material - forming an [Archimedes' Screw](https://en.wikipedia.org/wiki/Archimedes%27_screw).
