I have to get one of these fabbed believe it or not. I found some specs but they require some artistic license for the curves. Anyone have a PDF that I can print actual-size?

Do you have a compass, a pencil and a ruler? I'm not kidding, this is a 5 minute drafting exercise.

I'd be happy to model it in SolidWorks and send you a drawing. What's the actual ID within say, .025", the stud or bolt size and center-center distance, are they actually equidistant from the ID center, and how wide do you want the material surrounding the ID?

You mean something like this, right?

I realize it's not a big problem, the biggest is that you have to make an educated guess on the center and radius of the curves at the outer edges. The best I found so far is this:

I just want to remove as much potential for error as I can.

Take the picture you've got, and enlarge it on a photocopier. Set the enlargement percentage to equal the percentage necessary to make it the right size.

Done.

But I think you are over-thinking it. I can't think of a single situation where it would matter if the outside curves did not match.

Yeah guess I'll do the enlargement trick, thanks all.
