thanks,
i found those too... but i can´t convert to Step-format.
those are more like graphics formats, not actual CAD design formats. I would need something like .stp or .igs or parasolid or .sat or similar.
So i´d hope you guys have something.

If not, i will model it myself. Would take some time, but shouldn´t be a problem.
But i still hope someone could share. That would be my preferred option
