Another Rotring Cap, But Better

Hey folks, here is yet another Rotring 600 cap, but I believe my version is better. It is designed to be printed without supports, and it has a hole in the front which allows you to use the pencil even when the cap is on. For more precise drawing you can pull the cap off and use it in the normal configuration. I put mine into a drill and sand them down a bit to smooth the surfaces out and give them a matte surface. The Freecad file is included if you would like to mess with the design to make it better.
