rattleCAD, formerly a free and open-source CAD software for bicycle design, has undergone changes and is now considered proprietary software. As a result, the old source and binary files have been removed from its page on SourceForge, and a new official site has been launched. This page on Internet Archive serves as a backup for some source and binary releases, including free and demo versions of rattleCAD 4.x, for various operating systems. Users are encouraged to contribute to this collection by providing download links to their own rattleCAD versions not currently listed on the page.
