Would a standard Centronics parallel printer connector serve your needs and/or cost less?

The connector needs to be designed to work with a not-quite-centered insertion. Same reason the connector wiggles, that's the reason they need a connector designed specifically for the task. A Centronics connector requires the operator to carefully line it up when connecting- it most likely wouldn't work well in the sleeve.

In fact, it wouldn't surprise me if Hugo, the hacker that he is, already tried one just to see if it could be made to work.
