Customizable Shredder Blade
thingiverse
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.
With this file you will be able to print Customizable Shredder Blade with your 3D printer. Click on the button and save the file on your computer to work, edit or customize your design. You can also find more 3D designs for printers on Customizable Shredder Blade.
