It's a standard/coarse thread 9/16" hole, 15/16" total outside nut. The
damn nut is bigger than a walnut, so there's going to be a little work
welding a cap in there, then trimming it all down to a workable size. I'll
go to Ace and see if they have a thinner one that requires less machining.

For what I charge, I could just go buy a new opener. Good thing this isn't
for a real customer.

Why do we do that?

It's fun and challenging and most of all *Because we can*.
