Large Data PortThere are two different designs for the Large Data Port. The original BC version, now called CS:L (club spec legacy) and what was R2.0 and is now called CS:R (club spec revisited). The CS:R parts have been released in 3D format. If you are not familiar with the changes, or want 3D models of the CS:R parts, take a look at the DroidWiki article.
