About this 3D model

This is a customizable blade for a shredder, like the one in http://www.thingiverse.com/thing:356580. You can set: * the number of teeth * the angular width of teeth * the radial depth of teeth * the pitch of the teeth * the nut trap shape and diameter To use with a CNC, download the file, and run the program with thickness=0. This should create a 2D file that can be exported to DXF. Currently there is a bug using number_of_teeth=3 and 5, at least in OpenSCAD. EDIT: Teeth now have more material behind them, due to a 4 point tooth. EDIT(2014-07-16): fixed (read "hacked") bug for 3 and 5 tooth blades.
