I wanted to announce a new goody I have been working on the last days. Introducing, Screw ToolKit! The easy way to model screws in many types, sizes and variations. Download the file for free and alter the parameters in CINEMA 4D's attribute manager to model detailed screws in no time.
Update: The Screw Toolkit requires minimum CINEMA 4D R13. If you still use an older version you can download older but a bit buggy versions.
