About this 3D model

A simple way to change to belt extrusion for less noise and reduced wear. Includes a printable 80 tooth GT2 pulley.openSCAD parametric cad file included. Can be used to change number of teeth.Based on this very nice pulleys library:http://www.thingiverse.com/thing:16627UPDATE: There was a version posted with no holes and a thin back wall. It didn't work well since it flexed too much. It has now been removed. Thanks to turbotommi for testing. UPDATE 14/01: RobotDigg changed the GT2 belt pack. See instructions for details
