If you have a fine circle cutter that can do the radius this should be easy with thin styrene stock. Alternatively you can probably stencil it from the D rings. It's two concentric circles so it cannot be *that* hard.

It's not your idea that I commented on, but your apparently ill-informed belief that it wouldn't be a difficult task.
And you, missing the point entirely, wrote back:
Just because it's hard for you doesn't mean it's hard for me, you know, this is as subjective as it goes. Nothing to do with information, nor worth arguing about, unless you're trying to make your daily quota of negative internet comments.
It doesn't matter if it is easy for you. This was your suggestion to the OP to solve his own problem. It's a viable option if he has the equipment, the materials, and the skill, but making 20 of these (or even 4) cleanly and consistently is not trivial task. Your dismissive view of the difficulty involved can only be ascribed to ignorance.
I can demonstrate how it is done by making a couple of those for Russ since he's still missing them, if you're willing to make it worth my time.
Why on earth would I do that? You sound like you are one of those short-tempered people who turns everything into a wager or competition, and then a fight when they inevitably lose.
No, I already provided a practical solution to Ivanhoe6's problem. I'll stick with that.
