About this 3D model

I had some difficulties to get the wade screw ready properly. I tried the tap-method but was not successful so I decided to try the teeth version. This "thing" will show a method to get a desired amount of teeth into the bolt and how to divide the surface of this screw into exactly same sized teeth. You will find all about the wade extruder here: http://reprap.org/wiki/Wade's_Geared_Extruder ...and here on Thingiverse: http://www.thingiverse.com/thing:1794 Can actually also be used on other similar extruder designs.
