I've attached a thread file that contains non-standard metric threads that people have requested at various times on the forum. I've added your M32x1.25 thread to it. If you're 3D printing this you'll no doubt need to adjust the sizes to compensate for the inaccuracies associated with the process. I'll also post it to the thread that @jhackney1972 linked to.
If you're not sure what to do with the file you'll find the excellent ThreadKeeper add-in makes life a lot easier than doing things manually.
If this answers your question please mark the thread as solved as it can help others find solutions in the future.

If you need to know how to offset threads for 3D printing then I've created a guide here which you might find useful.
