Not for the CT-3. The pins are threaded on one end and screw into the press screw.
The cycling club at my undergrad definitely had a steel one, I'll see if anyone I know there can get to it and take a picture. It's entirely possible that it was made in the school machine shop by a fed up engineering student, and not purchased online. I do remember that it had a hex instead of that silly interface the aluminum ones have.
