Replacement Drive Unit for Kenwood attachment

I managed to break the drive gear on my Kenwood mixer attachment. So once i got my Rostock up and running I designed a replacement in openscad and printed a replacement.

This is the first thing I have designed so may not be 100%, and no doubt there is a better way to program the part, but this is a learning curve right ;) . I have included the scad file to allow you to change dimensions to suit.
