The original model on printables.com was designed for a Dewalt DCW604 router, however the guide rail was too loose on my DCW600B either because of differences in print or other factors. I included the new guide rail I made for my DCW600B as well as the original in case anyone needs it. I've also included the parametric file for the guide rail in case anyone needs to make modifications for their specific router.
You will need screws for mounting to the table and for holding the model together:
