A library to generate a printable 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.It works! -- I have succesfully printed a design made with this library on an Ultimaker. An overhang angle of 20° works just fine. If you know the overhang angle your printer is capable of, use that - otherwise try 20 or maybe 30 degrees. Why is this thing better than the MCAD auger in scew.scad? -- Cons: -- Future considerations: -- Notes: --
