I wanted to tackle that issue by using "square washers" instead ^{[I do know it's probably not worth the trouble to modify everything in order to integrate a different shape into the design, but it'll solve that problem completely]}.
^{Note: I'm not vouching for the website that I've included as an example.}

I didn't know these existed, but it seems an option as well! In general the cool thing about these products is that the price / weight of stainless steel is so so cheap. I don't think they would stay on a screw as nicely as round washers, but it would be doable. When I'll find time to sit at the CAD again, I might give it a shot, though I don't have such washers here to try / experiment with.

I don't really see another way to hold a round object in place other than friction to be honest.

It would be a significant amount of additional work for very marginal gains, but you could cut a small wedge out of each washer and modify your jig design so there is a small piece which sticks out in to the wedge cut-out to hold the washer in place. Almost certainly not worth the time, though. Your other option would be to buy square or other non-round washers, but again, you would obviously need to redesign your whole jig.

It sounds like your set up works fine with tape though. If you really mess up a washer by trying to punch it twice and being out of alignment, then you can just make a new one - it's not like you've messed up the entire back up as you might have done with a single steel plate.

I agree; the gain is small and it's really easy to put a piece of tape there. Or not, but then maybe only stamp a letter once. As you said, it's great that each word has its own washer with costs just a few pennies, so even if a letter comes crooked due to omitting tape, just take another washer. I have to say; I never had such a good looking steel backup..

I know, you can create a jig for a steel plate, but if you still mess up, you will need a new $20 plate.
